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.
