▎ 摘 要
NOVELTY - The utility model claims a copper-graphite oxide composite film, comprising a first copper foil layer, the graphene layer, and a second copper foil layer, the graphene layer is fixed between the first copper foil layer and second copper foil layer, the graphene film is fixed between the two layers of copper foil, which greatly improves the thermal conductivity of the composite film, good heat radiation effect and greatly improves the useful life of product.
