NOVELTY - Method of graphene modification of phthalocyanine blue pigment involves performing modification of phthalocyanine blue pigment with graphene by a non-covalent bond or a covalent bond-non-covalent bond force. USE - The method is useful for graphene modification of phthalocyanine blue pigment. ADVANTAGE - The method improves coloring ability of phthalocyanine blue, increases specific surface area of the pigment, reduces molecular aggregation between organic pigment compounds and obtains more concentrated particle size distribution of the pigment particles.
