Since graphene entered the public eye, it has shown broad prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery by virtue of its excellent optical, electrical, and mechanical properties.

In fact, graphene is known as the "king of new materials" with the highest strength, lightest weight, strongest toughness, best light transmittance, and best electrical and thermal conductivity known to mankind. With the efforts of many parties, the relevant research results of graphene have emerged, and have played a leading role in low-carbon life in many fields.

Wearable electronic devices are a popular technology product in recent years. Graphene has been proved to be an important element of wearable electronic devices due to its high conductivity, ultra-thin, flexible and strong characteristics.

The graphene flexible electrothermal film developed by Chinese R&D personnel can meet people's daily needs. At the same time, under different production methods, due to the need to produce flexible graphene heating films of various shapes, it can be used not only in smart wearable devices, but also as heating products in smart homes. It has three advantages of intelligent temperature control, energy saving and environmental protection, beautiful and practical .

The same is true for the graphene heating technology that shined during the Beijing Winter Olympics. Some people vividly describe the heating process of graphene in this way: as the material with the highest thermal conductivity, under the condition of electrification, the friction and collision between carbon molecular groups generate heat energy, and the heat energy is radiated uniformly in a planar manner through far infrared rays. Well accepted by the body, generating warmth from the inside out.

The clothes, scarves, socks, gloves and other clothing worn by relevant personnel in the Beijing Winter Olympics used the world's leading graphene textile flexible heating material. Graphene textile flexible heating material is a new type of material in the form of textile, which has both excellent heating performance and high-efficiency energy conversion. Not only has excellent thermal conductivity, but also has the advantages of washing resistance, softness, lightness, comfort and durability of ordinary fabrics.

Even after repeated washing, rubbing and cutting, the warmth retention ability remains. The related intelligent heating technology of graphene flexible fabric in low temperature environment has more applications than this. In the future, it will also provide more professional technical solutions and end products in the fields of automotive thermal management systems, special heating clothing for low-temperature environments, and medical and health equipment.
