NOVELTY - A graphene composite coating comprises 20-40 pts. wt. graphene, 10-20 pts. wt. nano polymer, 3-20 pts. wt. nano filler, 5-10 pts. wt. nano alumina, 10-20 pts. wt. organic fluorine-silicon modified acrylic resin, 5-20 pts. wt. a solvent, 10-20 pts. wt. a dispersant, 2-6 pts. wt. a defoamer, 3-5 pts. wt. a film-former, 3-5 pts. wt. an anti-settling agent. The nano- polymer comprises at least one of polyacetylene nano-fibers and polypyrrole nano-particles. USE - Graphene composite coating for heat dissipation shell used in heat dissipating device (claimed). ADVANTAGE - The graphene composite coating has excellent soaking effect, strong mechanical performance, excellent weather resistance and heat transfer is easy, and the coating is coated on the surface of the shell of the heat dissipation device, so that the heat dissipation effect is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the graphene composite coating, which involves mixing the above components; and (2) a heat dissipation device, which comprises heat dissipation shell, and the surface of the heat dissipation shell is at least partially coated with the graphene composite coating.
