NOVELTY - Preparing copper-graphene composite material involves utilizing mechanical alloying method to prepare copper and polymer powder to obtain copper-polymer powder, cold isostatic pressing the copper polymer powder to get a bar melting region to bar the porous rod material, carrying out heat treatment to the porous bar material to obtain an intermediate product, and hot-pressing and forming the intermediate product to obtain a final product. USE - Method for preparing copper-graphene composite material. ADVANTAGE - The method provides copper-graphene composite material with high operability, stable product quality, excellent conductivity and low manufacturing characteristics.
