▎ 摘  要

NOVELTY - The composite film has a first copper foil layer (1), a graphene layer (2), and a second copper foil layer (3) that are arranged in preset order. The graphene layer is fixed between the first copper foil layer and second copper foil layer. The thickness of the first copper foil layer is set as h1, the thickness of the second copper foil layer is set as h2, and the thickness of the graphene layer is set as h3. USE - Copper-graphite composite film. ADVANTAGE - The graphene film is fixed between the two layers of copper foil, so that the heat-conducting property of the composite film is greatly improved. The heat radiation effect is increased, so that the useful life of composite filmis greatly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of copper-graphite composite film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the copper-graphite composite film. Copper foil layers (1,3) Graphene layer (3)
