Composition for producing graphite-polymer composite and graphite-polymer composite produced therethrough

Abstract

Provided is a composition for producing a graphite-polymer composite. A composition for producing a graphite-polymer composite according to an embodiment of the present invention is prepared by comprising: a heat radiation filler comprising a non-insulating filler and an insulating filler, the non-insulating filler comprising a graphite composite including nanoparticles combined to a surface of graphite and a catechol amine layer; and a matrix forming component comprising a thermoplastic polymer compound. According to the present invention, the composition leads to an improvement in insulation property of a heat radiation member and a minimization in deterioration of heat radiation performance of the heat radiation member, so that the utilization of the composition can be improved in industries requiring both heat radiation characteristics and heat insulation performance. In addition, the composition is combined with a base material, and thus is easily modified through injection/extrusion or the like at the time of molding and can be modified into various shapes. The composite produced according to the present invention expresses excellent heat radiation performance, secures excellent mechanical strength, and has excellent lightweightness and excellent economic feasibility, and thus can be widely applied to various technical fields requiring heat radiation.
