Graphene dissipation structure

Abstract

Disclosed is a graphene dissipation structure including a substrate and a graphene dissipation layer. The substrate has at least two surfaces. One of the surfaces contacts at least one heat source, and another one is not in contact with the heat source and provided with the graphene dissipation layer, which includes surface-modified graphene nanometer sheets, a carrier resin and a filler. The surface-modified graphene nanometer sheets are well dispersed in the carrier resin, and enhanced to contact each other through the filler to form a thermal conductive network. The ratio of the particle size of the filler and the thickness of the graphene nanometer sheets is about 2 to 100. Therefore, the heat absorbed by the substrate from the heat source is transferred to the graphene dissipation layer, and further dissipated to the outside through thermal conduction or radiation, thereby achieving the function of heat dissipation.
