Graphene-the "black gold" of the 21st century, the king of new materials, is a new type of nano material with good thinness,lightness, strength, toughness, and good electrical and thermal conductivity among the known nature.
The graphene conductive layer has very good electrical conductivity, thermal conductivity, mechanical properties, etc., and is very flexible.
The strength of graphene is as high as 130GPa, which is one of the materials with the best mechanical properties found so far. The thermal conductivity of graphene is 5000W/(m·K), which is a good heat conductor.
