NOVELTY - The preparation method of graphene coating material involves adding graphene surface modified by the covalent bond of the amine organic molecule to curing agent, stirring, uniformly dispersing, adding to epoxy resin, and stirring, where depending on the type of coating, the amount of solvent to be added is determined. USE - Preparation method of graphene coating material. ADVANTAGE - The method enables preparation of graphene coating material with stable dispersibility, which breaks the interface bonding problem introduced by addition of graphene in coating, and lays down a solid foundation for construction of a high-density graphene physical shielding structure or a three-dimensional network conducting structure.
