Graphene-modified heat conduction film

The present invention relates to a graphene-modified heat conduction film, which comprises, by weight, 10-60% of a polyimide emulsion, 0-10% of a binder, 30-90% of graphene, 0-5% of an auxiliary agent and 0-10% of a solvent. According to the present invention, based on characteristics of high strength, high specific surface area, high chemical reaction activity, high thermal conductivity coefficient and high filling property of graphene, the heat conduction film is added with graphene so as to improve the strength of the heat conduction film, and the graphene has the good lubrication effect so as to improve the mechanical property and the thermal conductivity of the heat conduction film.
