▎ 摘　　要

NOVELTY - A graphene copper-based reinforced thermal conductive film is prepared by taking foamed copper powder, pre-treating, chemically depositing with graphene to obtain graphene composite foamed copper powder, mixing with foamed graphene powder, adding graphene/pure copper mixed powder, ball milling, vapor-depositing with copper, mixing, spreading onto flat mold bottom, covering upper surface with copper foil, casting copper liquid under oscillating conditions, and lowering temperature by program under the conditions of vacuum oscillation. USE - The method for preparing graphene copper-based reinforced thermal conductive film. ADVANTAGE - The method does not involve electroplating process, has low energy consumption, is environment-friendly, relatively stable heat conducting film structure, high strength, excellent mechanical property, high film size controllability, and the size is increased, mechanical and electrical performance is stable, and is suitable for each field.
