Abstract
A graphene copper composite material preparation method based on a combination of hot pressing sintering and chemical vapor deposition, comprising: presetting multi-layer copper foil in a hot pressing chamber; preparing a graphene thin film on the surface of the copper foil by means of a chemical vapor deposition method to obtain a graphene copper composite material; and then performing hot pressing forming on the multi-layer graphene copper foil material to prepare the graphene copper composite material. Said material can replace a traditional copper material or silver material, is applied to a supercapacitor or a motor driving device, and has the effects of improving efficiency, reducing temperature rise, etc.
