Beschreibung
Zusammenfassung:	The invention discloses a metal-based graphene composite heat dissipation material and a preparation and test method thereof, the composite heat dissipation material comprises a graphene layer and a metal foil layer, and the graphene layer and the metal foil layer are attached to each other. The outer side face of a metal foil layer in the metal-based graphene composite heat dissipation material is evenly coated with a layer of silver silicone grease, then the outer side face of a graphene layer in the metal-based graphene composite heat dissipation material is heated, meanwhile, an infrared thermal imager is used for measuring the silver silicone grease side, and the metal-based graphene composite heat dissipation material is obtained. The heating process of the metal-based graphene composite heat dissipation material can be obtained, and the temperature and the heating rate are stabilized. According to the method, the metal surface is uniformly coated with the silver silicone grease layer, so that the diffi
