▎ 摘　　要

NOVELTY - A method for improving the graphene-metal conductivity interface in cables comprises adsorbing a layer of molecules or multiple layers of molecules on the inner surface of the pores of a foam metal; pressing and filling the graphene powder into the pores of the foam metal; stacking and compacting multiple foam metal sheets to produce a flat graphene-metal composite cable. USE - Method of graphene-metal conductive interface in cable. ADVANTAGE - The method modifies the metal ion-containing conjugated molecule on the surface of the foam metal of the alloy material, improves the graphite powder and metal in the metal graphene of the contact characteristics, and improves the performance of the cable.
