▎ 摘　　要

NOVELTY - The present invention discloses a graphene powder coating material including surface modified graphene platelets and a curable resin, which are well mixed. The graphene powder coating material is coated on a target substrate through an electrostatic spraying process so as to solve the problems of the electrostatic spraying process by use of excellent properties of electrical and thermal conductivities provided by the graphene platelets. Therefore, thermal dissipation, anti-oxidation and acid-alkali resistance for the target substrate are achieved.
