▎ 摘 要
NOVELTY - Performing graphene copper composite material, comprises (i) performing chemical vapor deposition on the copper powder under methane and a reducing atmosphere to form graphene on the surface of the copper powder to obtain the first powder, where the purity of the copper powder is not less than 99.8%, and the oxygen content of the copper powder is not more than 0.1%; and (ii) hot-pressing and sintering first powder and drawing after sintering. The reducing gas is hydrogen. USE - The composite material is useful in transmission cable (claimed). ADVANTAGE - The copper graphene composite material has excellent room temperature conductivity on the rice length. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene of copper composite material.
