NOVELTY - The utility model belongs to electric material field, specifically relates to a graphene electro-thermal film, comprising orderly arranged insulating layer, prepreg layer, a heat insulation layer, an insulating layer with graphene heat-emitting layer toward the joint surface of the prepreg layer. graphene emitting size of insulating layer is less than the size of the insulating layer so that the surface of the insulating layer on graphene two sides of the heat-generating layer with reserved bit, graphene heating layer reserved bit of two sides are respectively provided with a conductive metal, a conductive metal bar is clamped between the insulating layer and the prepreg layer. conductive metal strip for external power supply, an insulating layer graphene heating layer, a prepreg layer, a thermal insulation layer between the hot-pressing connection. A graphene electro-thermal film of the utility model, the cost is low, the structure is simple, it has strong rigidity, while promoting heat-transfer the heat energy loss is reduced.
