NOVELTY - The utility model claims a heat radiating material technology field, especially relates to a composite heat-conducting graphite film material, comprising copper foil and adhered on the copper foil surface of the graphite film, the graphite film surface has several through holes, in the through hole is filled with vertical growth of graphene or carbon nanotubes. The utility model claims a composite heat-conducting graphite film material, graphite film surface is provided with several through holes, in filling a vertical growth of graphene or carbon nanometre tube, graphite film interlayer heat can be quickly diffused, filled in the through hole of the vertical growth of graphene or carbon nanometre pipe transmits the heat in the interlayer, and finally through copper foil heat conduction to realize fast heat radiating effect.
