[0002] Graphene is a honeycomb-shaped planar film formed by carbon atoms in an sp2 hybrid manner. It is a quasi-two-dimensional material with a thickness of only one atomic layer. As an emerging material, graphene is widely used in various fields such as life, industry and agriculture, and medical treatment due to its super strong electrical conductivity, thermal conductivity, light transmittance, flexibility and other characteristics. As a heating material with unlimited potential, electric heating film is widely used in life fields such as building heating, heating floors, far-infrared health care rooms, as well as industrial fields such as paint rooms and drying rooms.
