Beschreibung
Zusammenfassung:	A method for preparing a graphene/metal composite sheet includes adding polyvinyl alcohol into distilled water and heat to about 100° C. under stirring to prepare a polyvinyl alcohol solution; dispersing graphene in distilled water using ultrasonication to prepare a graphene solution; mixing the polyvinyl alcohol solution and the graphene solution to form a graphene/polyvinyl alcohol mixed slurry; after a metal sheet is subjected to a surface activation treatment, coating the graphene/polyvinyl alcohol mixed slurry onto the metal sheet at both upper and lower surfaces; vacuum sintering to remove the polyvinyl alcohol in the surface coating to obtain a graphene/metal plate; overlaying at least two graphene/metal plates and bonding them together via hot isostatic pressing to form multilayer graphene/metal plates; and hot rolling the bonded multilayer graphene/metal plates to form the graphene/metal composite sheet.
