▎ 摘　　要

NOVELTY - Preparation of copper/graphene composite material with network interpenetrating structure, which involves S1, impregnating the foamed copper with the graphene oxide aqueous dispersion, drying, and then repeating the above-mentioned impregnation-drying operation several times until the foamed copper no longer gains weight, obtaining graphene oxide-filled foamed copper, and S2, subjecting the graphene oxide-filled copper foam prepared in step S1 to cold-pressing pre-forming and hot-pressing in sequence. USE - Preparation of copper/graphene composite material with network interpenetrating structure. ADVANTAGE - The method has mild preparation condition, simple operation and easy implementation, does not need special device, uses conventional hot pressing device, and greatly reduces production cost of copper/graphene composite material with network interpenetrating structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a composite material, which comprises copper and graphene. The copper and graphene in the composite material are both continuous phases. The copper and the graphene intersect each other to form a network interpenetrating structure.
