Description

technical field [0001] The invention relates to a composite material, in particular to a graphene composite material with high conductivity. Background technique [0002] Graphene is the thinnest and hardest nano-material known in the world. It is almost completely transparent and only absorbs 2.3% of light; its thermal conductivity is as high as 5300W / m K, which is higher than that of carbon nanotubes and diamonds. The electron mobility exceeds 15000cm2 / V·s, which is higher than carbon nanotubes or silicon crystals, and the resistivity is only about 10-8Ω·m, which is lower than copper or silver. It is the material with the smallest resistivity in the world. As a new type of nanomaterial with the thinnest, hardest, and strongest electrical and thermal conductivity found so far, graphene is called "black gold" and "the king of new materials". [0003] Using pure graphene as conductive material, the production cost is high; therefore, utilizing the high conductivity of graphe...
