NOVELTY - The utility model claims a graphene coated composite heat-conducting filler, wherein it comprises orderly covering the copper powder layer, the coupling agent layer, the graphene layer and organic coating layer. This utility model of graphene coated composite heat-conducting filler with excellent heat-conducting performance, copper powder is not easy to be oxidized, good radiation performance, can be widely used for all kinds of conducting macromolecular material such as composite heat-conducting plastic, so the composite heat-conducting plastic with high thermal conductivity and high radiation performance, solves the problem that the metal composite heat-conducting plastic metal easy to oxidize, poor dispersing effect caused by heat conduction effect is not good.
