▎ 摘　　要

NOVELTY - A graphene heat dissipation coating comprises graphene oxide. The graphene oxide is a layered structure comprising edge region and conjugate region. The edge area is distributed with carboxyl. The conjugated region is distributed with hydroxyl. At least portion of the conjugated regions are adsorbed and fixed with spherical nano metal oxides, and at least portion of the conjugated regions are not adsorbed and fixed with spherical nano metal oxides. The plane of the conjugate region which adsorbs and fixes the spherical nano metal oxide is convex. The plane of the conjugated region which is not adsorbed and fixed with the spherical nano metal oxide is sunken. The two form the graphene oxide surface with corrugated structure. USE - Graphene heat dissipation coating used for electronic devices. ADVANTAGE - The graphene heat dissipation coating has excellent heat dissipation performance, heat radiation balance growth and fast radiating effect.
