Problem, this utility model provide a kind of compound conductive graphite membrane material, and graphite film surface has some through holes, through hole
It is interior filled with orthotropic Graphene or CNT, graphite film interlayer heat can spread rapidly, by filling out in through hole
Heat is transmitted by the orthotropic Graphene or CNT for filling in interlayer, finally by Copper Foil heat conduction, realizes quick heat radiating
Effect.
This utility model solves the technical scheme adopted by its technical problem：A kind of compound conductive graphite membrane material,
Including Copper Foil and the graphite film for being attached to copper foil surface, the graphite film surface has some through holes, fills out in the through hole
Filled with orthotropic Graphene or CNT.
The graphite film for preparing is obtained into through hole by punching press, then Copper Foil is attached in the side of conduction graphite film,
With Copper Foil as substrate, with CVD vertical-growth, Graphene or CNT in the hole of graphite film.
Specifically, the graphite film thickness is 0.01-0.1mm.
Specifically, some through holes are evenly distributed on graphite film surface.
Preferably, the graphite film surface is also pasted with layer protective layer.Protective layer can be PET film layer or other can
It is attached to the film on graphite film surface.
Preferably, the Copper Foil lower surface is sequentially provided with adhesive tape and mould release membrance.Wherein adhesive tape is bond plies, release
Film is PET mould release membrances.
The beneficial effects of the utility model are：A kind of compound conductive graphite membrane material that this utility model is provided, graphite
Film surface has in some through holes, through hole filled with orthotropic Graphene or CNT, graphite film interlayer heat
Can spread rapidly, heat be transmitted in interlayer by the orthotropic Graphene or CNT filled in through hole, most
Afterwards by Copper Foil heat conduction, the effect of quick heat radiating is realized, the heat conductivility of vertical direction is effectively increased, LED etc. is can be applicable to
The high field of cooling requirements.
