NOVELTY - The utility model claims a metal composite belt, specifically relates to a double-layer graphene copper foil composite belt. A double-layer graphene copper foil composite belt, comprising a copper foil base material layer, a graphene base material layer, an adhesive layer and a release material layer, the graphene base material layer is grown on the upper and lower surface of the copper foil base material layer by CVD chemical vapour deposition method, the graphene base material layer is adhered with a release material layer through the adhesive layer. The graphene substrate layer of the utility model is grown on the upper and lower surfaces of the aluminium foil by CVD; compared with the original single-layer copper foil, it has better shielding effect; and the graphene substrate layer can quickly radiate; it increases the applicability of the product; at the same time, it can improve the elastic and anti-aging performance of the whole composite belt.
