1.1 Research Background and Significance
In recent years, with the continuous development of materials science, graphene, a two - dimensional carbon nanomaterial, has attracted extensive attention due to its excellent physical properties. Graphene has a unique honeycomb - like structure composed of a single layer of carbon atoms, endowing it with remarkable electrical conductivity, thermal conductivity, high strength, and flexibility. Its thermal conductivity is extremely high, reaching up to 5300 W/(m·K) at room temperature, which is much higher than that of traditional heat - conducting materials such as copper and aluminum. In terms of electrical conductivity, it shows excellent performance similar to that of metals, with a carrier mobility as high as 200000 cm²/(V·s) at room temperature.
The application of graphene in the field of household items has become a research hotspot. Traditional household heating and functional products often have some limitations. For example, traditional heating methods such as electric heating wires in electric blankets may have problems such as uneven heating, short service life, and potential safety hazards. In the context of the growing demand for high - quality, energy - efficient, and intelligent household products, the use of graphene's excellent thermal and electrical conductivity to develop new - type household items has important practical significance.
From a market perspective, the global household products market is huge and constantly evolving. Consumers are increasingly demanding products with better performance, energy - saving features, and added value. Graphene - based household items can meet these demands to a certain extent. For instance, graphene - enhanced heating products can heat up faster, save energy, and provide a more comfortable heating experience. This not only meets the needs of consumers but also has broad market prospects, which can drive the development of related industries and create new economic growth points.
1.2 Research Objectives and Scope
The main objective of this study is to comprehensively and in - depth analyze the application status and potential of graphene in various household items.

Through the study of these products, we can fully understand the application value and development potential of graphene in the household item market.
2. Properties of Graphene: Thermal and Electrical Conductivity
2.1 Thermal Conductivity
2.1.1 Principle of High Thermal Conductivity
Graphene's high thermal conductivity is attributed to its unique atomic structure and phonon - mediated heat transfer mechanism. Structurally, graphene consists of a single layer of carbon atoms arranged in a hexagonal honeycomb lattice. The strong covalent bonds between carbon atoms in the plane endow the structure with high stability.
In the process of heat conduction, phonons play a crucial role. Phonons are quantized lattice vibrations. In graphene, due to its two - dimensional structure and high - symmetry lattice, the acoustic phonons, especially the out - of - plane acoustic (ZA) phonons, in - plane transverse acoustic (TA) phonons, and in - plane longitudinal acoustic (LA) phonons, have long mean free paths. Among them, the ZA phonons are found to contribute significantly to heat conduction, accounting for a large proportion (up to 75% according to some studies). The long - wavelength acoustic phonons in graphene can travel long distances with little scattering, enabling efficient heat transfer. This unique phonon behavior allows graphene to have a thermal conductivity as high as 5300 W/(m·K) at room temperature, making it one of the best - performing thermal - conducting materials known.
2.1.2 Comparison with Traditional Materials
When compared with traditional heat - conducting materials used in household items, such as metals (e.g., copper with a thermal conductivity of about 401 W/(m·K) at room temperature) and ceramics, graphene shows distinct advantages.
In terms of thermal conductivity, as mentioned above, graphene's thermal conductivity is much higher than that of copper. For ceramics, although some high - thermal - conductivity ceramics can reach thermal conductivities in the range of several hundred W/(m·K), they are still far behind graphene. In addition to the high thermal conductivity, graphene also has better thermal stability than some traditional materials. Metals like aluminum may experience softening or oxidation at relatively high temperatures, affecting their heat - conducting performance. Graphene, on the other hand, can maintain its structural integrity and high - thermal - conductivity performance at higher temperatures due to the strong covalent bonds in its structure.
Moreover, graphene's flexibility is another advantage over brittle ceramics. This flexibility makes it more suitable for applications in some flexible household items, such as flexible heating pads and blankets, where the material needs to adapt to different shapes and bending requirements during use.
2.2 Electrical Conductivity
2.2.1 Unique Electronic Structure
Graphene's excellent electrical conductivity is closely related to its unique electronic structure. In the graphene lattice, each carbon atom is covalently bonded to three adjacent carbon atoms through sp² hybridization, forming a planar hexagonal structure. The remaining unhybridized p - orbital electrons of each carbon atom are delocalized and form a conjugated π - electron system that extends over the entire two - dimensional plane.
These delocalized π - electrons are highly mobile and can move freely in the plane of graphene. The energy - momentum relationship of electrons in graphene shows a linear dispersion near the Fermi level, and the electrons in graphene behave like massless Dirac fermions. This unique electronic behavior results in an extremely high electron mobility in graphene, with a carrier mobility as high as 200000 cm²/(V·s) at room temperature. Such high - mobility electrons enable graphene to have excellent electrical conductivity, comparable to that of some metals.
2.2.2 Significance in Heating Applications
In heating - type household items, such as electric blankets, floor heating films, and physiotherapy pads, graphene's good electrical conductivity is of great significance. When an electric current is applied to graphene - based heating elements, due to its high electrical conductivity, the resistance is relatively low. According to Joule's law (\(Q = I^{2}Rt\), where \(Q\) is the heat generated, \(I\) is the current, \(R\) is the resistance, and \(t\) is the time), a lower resistance means that less energy is wasted in the form of resistance heat during the passage of current.
Moreover, the uniform distribution of electrons in graphene due to its excellent conductivity enables uniform heating. For example, in an electric blanket made of graphene, the heat can be evenly distributed across the surface of the blanket, providing a more comfortable heating experience for users, which is different from traditional electric heating wires that may cause local over - heating or uneven heating problems. In floor heating films, graphene's good electrical conductivity can ensure that the floor heats up quickly and evenly, improving the efficiency and comfort of floor heating systems.
3. Application in Specific Home Furnishings
3.1 Electric Blankets
3.1.1 Heating Mechanism
Graphene electric blankets utilize the excellent electrical and thermal conductivity of graphene. When an electric current passes through the graphene - based heating element in the electric blanket, due to its high electrical conductivity, electrons move freely in the graphene lattice. According to Joule's law (\(Q = I^{2}Rt\)), the resistance of the graphene - based heating element causes the conversion of electrical energy into heat energy. The high - mobility electrons in graphene can quickly transfer the generated heat energy. Then, because of graphene's high thermal conductivity, the heat is rapidly and evenly distributed across the entire surface of the electric blanket. For example, the graphene heating element in the electric blanket can be designed as a thin - film structure, and once the current is applied, the heat generated by the graphene heating film can be transferred to the fabric of the electric blanket and then to the human body in contact with the electric blanket, providing a warm environment.
3.1.2 Advantages over Traditional Electric Blankets
Compared with traditional electric blankets, graphene - based electric blankets have several significant advantages. In terms of safety, traditional electric blankets often use metal heating wires, which may have potential safety hazards such as over - heating, short - circuiting, and even fire risks due to the long - term use and wear of the wires. Graphene electric blankets, on the other hand, have a more uniform heating effect, reducing the risk of local over - heating. For example, the Xiaomi Smart - Controlled Constant - Temperature and Fast - Heating Electric Blanket uses a graphene thermal superconducting film. Its uniform heating property not only improves safety but also eliminates the electromagnetic radiation problems associated with traditional heating wires, making it safer for users, especially for pregnant women, the elderly, and children.
In terms of heating speed, graphene's high thermal conductivity enables graphene electric blankets to heat up much faster. Traditional electric blankets may take 15 - 30 minutes to reach the desired temperature, while graphene electric blankets can reach the set temperature within 5 - 10 minutes. This rapid heating feature allows users to quickly enjoy a warm environment, saving waiting time.
Energy - saving is another advantage. Graphene electric blankets are more energy - efficient. The Xiaomi electric blanket mentioned above is equipped with an IGBT energy - saving constant - temperature chip. After the indoor temperature reaches the set value, the chip can automatically reduce the power, maintaining a constant temperature with an hourly power consumption of only 0.2 degrees. In contrast, traditional electric blankets consume more power to maintain the same heating effect, increasing energy costs.
In addition, graphene electric blankets are often more convenient to clean. Some graphene electric blankets can be machine - washed after removing the heating element, while traditional electric blankets are usually not suitable for direct machine - washing due to the presence of heating wires, which may be damaged during the washing process.
3.1.3 Market Products and User Feedback
In the market, there are several well - known graphene electric blanket products. The ENELCA electric blanket from Italy is a high - end product. It is made of carbon fiber material with a graphene inner core. This product has obtained multiple international detection standard certifications, such as the EU CB standard, the South Korean KC standard, and the Italian fire - resistance certification. These certifications ensure the product's quality and safety.
User feedback on ENELCA electric blankets is generally positive. Many users praise its fast heating speed. It can heat up all over in 10 seconds and become warm in 30 seconds, which meets the need for quick heating. The feature of independent temperature control in different zones is also well - received. It has two sets of power adapters and controllers, allowing users on both sides of the double - bed to adjust the temperature according to their own preferences. For example, a couple may have different temperature requirements, and this function can well meet their individual needs. Moreover, the product's low - voltage operation (12V) makes users feel safe, and the far - infrared waves emitted by graphene can promote blood circulation, which is considered beneficial for health, especially for the elderly with rheumatism or women during menstruation.
Another popular product is the Xiaomi Smart - Controlled Constant - Temperature and Fast - Heating Electric Blanket. Users like its intelligent functions, such as independent left - right temperature control and a 1 - 12 - hour intelligent timing function. The waterproof design (PX8 waterproof level) also makes users feel at ease during use and cleaning. However, some users also point out that compared with traditional electric blankets, the price of graphene electric blankets is relatively high, which may be a factor restricting their wider use.
3.2 Pillows and Cushions
3.2.1 Design and Function in Pillows
Take the graphene - heated neck pillow as an example. Its design combines ergonomics and the unique properties of graphene. The outer fabric of the neck pillow is usually made of soft and skin - friendly materials such as super - soft fleece, which provides a comfortable touch. Inside, it is filled with materials like memory foam or foam particles to provide good support for the neck.
The key component is the graphene - based heating element. Graphene's excellent electrical and thermal conductivity is utilized here. When connected to a power source (usually through a USB interface and a mobile power supply), an electric current passes through the graphene heating element. Due to its high electrical conductivity, the graphene heating element quickly generates heat according to Joule's law. Then, the high - thermal - conductivity of graphene enables the heat to be evenly distributed around the neck area.
Moreover, some advanced graphene - heated neck pillows also integrate massage functions. Small vibration motors can be installed inside the neck pillow. Combined with the heating function of graphene, it can not only warm the neck but also relieve neck fatigue through vibration massage. For example, the Aika graphene cloud neck pillow has a unique cloud - like shape. It uses AIHF graphene - heating fiber. With a 2500 - mAh mobile power supply, it can achieve three - level temperature adjustment (40°C, 45°C, and 55°C). The low - temperature gear (40°C) provides a comfortable warm feeling, which is suitable for daily use; the medium - temperature gear (45°C) can relieve neck stiffness caused by long - term computer use; and the high - temperature gear (55°C) is more effective in relieving neck pain. This multi - function design greatly improves the user experience, especially for people who often have neck problems due to long - term sedentary work or driving.
3.2.2 Application in Cushions (Car and Home)
In car cushions, graphene is mainly used to improve heating efficiency and comfort. The graphene - based heating element in the car cushion is usually evenly distributed in the cushion. When the car's power supply is connected, the graphene heating element conducts electricity and generates heat. Because of graphene's high thermal conductivity, the heat can be quickly transferred to the surface of the cushion, making the seat warm up rapidly. This is very practical in cold weather, allowing drivers and passengers to enjoy a warm sitting experience as soon as they get in the car.
For home cushions, graphene also plays an important role. In winter, when people sit on the sofa or chair, a graphene - heated cushion can provide warmth. Similar to car cushions, the graphene heating element in home cushions uses its electrical and thermal conductivity to generate and transfer heat. The difference is that home cushions may have more diverse power - supply methods, such as using a wall - mounted power adapter. For example, some home - use graphene - heated cushions can be adjusted in multiple temperature levels through a controller, allowing users to choose the appropriate temperature according to the indoor temperature and personal needs.
Compared with traditional cushions with resistance - wire heating, graphene - heated cushions have obvious advantages. Traditional resistance - wire heating cushions often have problems such as uneven heating. The heating area is mainly concentrated around the resistance wires, and there are large temperature differences in different parts of the cushion, which affects the comfort of use. In contrast, graphene - heated cushions can achieve more uniform heating due to the excellent thermal conductivity of graphene, providing users with a more comfortable sitting experience.
3.3 Snow - Melting Mats
3.3.1 Working Principle for Snow Melting
Graphene snow - melting mats work based on the principle of using graphene's electrical conductivity to generate heat. When an electric current is applied to the graphene - based heating element in the snow - melting mat, due to the electrical resistance of graphene, the electrical energy is converted into heat energy according to Joule's law (\(Q = I^{2}Rt\)). The generated heat is then transferred to the surface of the snow - melting mat.
The heat on the surface of the mat can melt the snow and ice in contact with it. In different environmental conditions, the performance of graphene snow - melting mats also shows certain adaptability. In areas with heavy snowfall, the snow - melting mat can be adjusted to a higher power to ensure that the heat generated can quickly melt the accumulated snow. In relatively cold but less - snowy areas, the snow - melting mat can work at a lower power to maintain a certain surface temperature to prevent ice formation. For example, in some northern regions of China where the winter is cold and snowy, graphene snow - melting mats can be installed on roads, sidewalks, and the entrances of buildings. When the snow - melting mat is powered on, the heat generated by the graphene heating element can quickly melt the snow on it, ensuring the normal passage of people and vehicles.
3.3.2 Installation and Maintenance
The installation of snow - melting mats is relatively simple. For outdoor applications such as roads, the snow - melting mat can be laid on the ground surface before paving the road surface materials, or it can be installed on the existing road surface by using special fixing devices. For example, in the installation of a snow - melting mat on a sidewalk, first, the surface of the sidewalk is cleaned to ensure flatness. Then, the snow - melting mat is laid flat and fixed with adhesive or small - sized fixing nails. The power - supply lines of the snow - melting mat are connected to a stable power source, usually through a waterproof junction box to ensure safety.
In terms of maintenance, regular inspections are required. Check whether the heating element of the snow - melting mat is damaged, whether the power - supply lines are intact, and whether there is water leakage in the waterproof junction box. If any problems are found, they should be repaired or replaced in time. In addition, in summer when the snow - melting mat is not in use, it can be properly stored to prevent damage from sunlight and rain. Overall, compared with traditional snow - melting methods such as using snow - melting agents, graphene snow - melting mats are more environmentally friendly and require less manual intervention in the snow - melting process, which is more convenient and efficient in practical use scenarios.
3.4 Floor Heating Films
3.4.1 Heating System Composition
A graphene floor heating film system mainly consists of several key components. The core component is the graphene - based heating film. The graphene heating film is usually made by uniformly dispersing graphene materials on a flexible substrate, such as a polymer film. This structure enables the heating film to have both good flexibility and excellent electrical and thermal conductivity.
In addition, a thermostat is an essential part of the system. The thermostat is used to control the temperature of the floor heating film. It can sense the temperature of the indoor environment and the floor surface. According to the set temperature value, the thermostat adjusts the power supply to the graphene heating film. For example, when the indoor temperature is lower than the set value, the thermostat increases the power supply to the heating film, so that the heating film generates more heat to raise the indoor temperature; when the indoor temperature reaches the set value, the thermostat reduces the power supply to maintain a constant temperature.
There are also other auxiliary components, such as insulation layers. The insulation layer is usually installed under the graphene heating film to prevent heat from being transferred downward, improving the heating efficiency of the floor heating system. The wiring system is responsible for connecting the heating film, thermostat, and power source to ensure the normal operation of the entire heating system.
3.4.2 Energy - Saving and Comfort Advantages
Graphene floor heating films have significant energy - saving advantages. Firstly, due to graphene's high electrical conductivity, the resistance of the graphene heating film is relatively low. According to Joule's law, less energy is wasted in the form of resistance heat during the heating process. Secondly, the high thermal conductivity of graphene allows the heat generated by the heating film to be quickly and evenly transferred to the floor surface and then to the indoor air, reducing the heating time required to reach the set temperature. For example, compared with traditional heating methods such as air - conditioners, graphene floor heating films can save about 30% - 40% of energy consumption under the same heating effect.
In terms of comfort, graphene floor heating films provide a more comfortable heating experience. They achieve uniform heating across the entire floor surface, avoiding the problem of uneven heating in some traditional heating methods. The heat is transferred from the bottom up, which is in line with the principle of human body comfort, making people feel warm from the feet up. Moreover, graphene heating films can also emit far - infrared rays during the heating process. These far - infrared rays have a wavelength of 6 - 16μm, which is close to the wavelength of the human body's own radiation. They can be absorbed by the human body, promote blood circulation, and enhance metabolism, which is beneficial to human health.
3.4.3 Installation Process and Precautions
The installation process of graphene floor heating films is as follows: First, the floor surface needs to be leveled and cleaned to ensure that there are no bumps or debris. Then, an insulation layer is laid. The insulation layer can be made of materials such as extruded polystyrene boards, which play a role in preventing heat loss. Next, the graphene heating film is laid on the insulation layer. When laying, it should be ensured that the heating film is flat and there are no wrinkles or overlaps. The joints of the heating film should be properly connected to ensure good electrical conductivity.
After that, a layer of heat - conducting floor - covering material is laid on the heating film, such as floor tiles or wooden floors. During the connection of the wiring, it is necessary to ensure that the wires are correctly connected to the heating film and the thermostat, and the wiring should be carried out in accordance with the electrical safety standards.
During the installation process, several precautions need to be noted. First, avoid damaging the graphene heating film during the installation. Sharp tools should not be used to scratch or pierce the heating film. Second, ensure the waterproofing of the installation area. If water enters the heating film or the wiring system, it may cause short - circuits and other safety hazards. Third, the installation of the thermostat should be carried out in a position where it can accurately sense the indoor temperature, usually on the wall at a height of about 1.5 meters from the ground.
3.5 Other Applications (Pipe Heating Mats, Planting Mats, Physiotherapy Mats, Sauna Blankets)
3.5.1 Pipe Heating Mats
Graphene is applied in pipe heating mats to prevent pipes from freezing and maintain the temperature of liquid transportation. The application principle is based on graphene's electrical and thermal conductivity. The pipe heating mat with a graphene - based heating element is wrapped around the pipeline. When an electric current is applied, the graphene heating element generates heat due to its electrical resistance. The generated heat is then transferred to the pipeline through heat conduction.
In cold winter, when the ambient temperature is low, water in the pipeline is likely to freeze, which may cause the pipeline to burst. The heat generated by the graphene - heated pipe heating mat can keep the temperature of the pipeline above the freezing point of water, ensuring the normal flow of the liquid in the pipeline. For example, in some rural areas where water pipelines are exposed outdoors, installing graphene - heated pipe heating mats can effectively prevent the pipelines from freezing, ensuring the normal supply of domestic water.
3.5.2 Planting Mats
Graphene planting mats can create a suitable temperature environment for plant growth. The graphene - based heating element in the planting mat is designed to generate a certain amount of heat when powered on. The heat is evenly distributed on the surface of the planting mat.
Plants have specific temperature requirements during their growth process. For some plants that are sensitive to temperature, especially in cold weather or in areas with large temperature differences between day and night, the heat provided by the graphene planting mat can help maintain a relatively stable root - zone temperature. This stable temperature environment is conducive to the growth and development of plant roots, promoting the absorption of water and nutrients by plants. For example, in greenhouse planting, using graphene planting mats can adjust the temperature of the root zone of plants, making plants grow better and increasing crop yields.
3.5.3 Physiotherapy Mats
Graphene physiotherapy mats work based on the principle of far - infrared radiation. Graphene can emit far - infrared rays with a wavelength range of 6 - 16μm when heated. These far - infrared rays are very similar to the far - infrared rays emitted by the human body. When the human body is in contact with the graphene physiotherapy mat, the far - infrared rays can be absorbed by the human body.
The absorption of far - infrared rays by the human body can promote blood circulation. It makes the blood vessels dilate, increasing the blood flow rate and improving the oxygen - carrying capacity of the blood. At the same time, it can also enhance metabolism, accelerating the decomposition and utilization of nutrients in the body, and promoting the elimination of waste products. For people with poor blood circulation, such as the elderly and those with cardiovascular and cerebrovascular diseases, using a graphene physiotherapy mat regularly can play a certain role in health care and physical therapy, relieving symptoms such as cold hands and feet and joint pain.
3.5.4 Sauna Blankets
Graphene sauna blankets use the electrical and thermal conductivity of graphene to generate heat. When an electric current passes through the graphene - based heating element in the sauna blanket, heat is generated according to Joule's law. The heat is retained inside the sauna blanket, creating a high - temperature environment similar to a traditional sauna.
Users can lie inside the graphene sauna blanket to enjoy the sauna - like experience at home. The advantage of graphene sauna blankets is that they are more convenient and private than going to a public sauna. In addition, the far - infrared rays emitted by graphene during the heating process can also penetrate the skin, promoting sweating, detoxification, and relaxation of the body. For example, after a day of fatigue, using a graphene sauna blanket can help relieve muscle fatigue, improve sleep quality, and enhance the body's immunity.
