▎ 摘　　要

NOVELTY - Graphene complex powder comprises graphene and graphene oxide, the graphene oxide is coated on the surface of the graphene, after the graphene oxide is coated on the surface of the graphene, it is spray-dried at greater than 100℃, and then, the surface is modified by amination under an ammonia plasma atmosphere. USE - The graphene complex powder is useful in electrophoretic paint (claimed). ADVANTAGE - The graphene complex powder has good anti-corrosion performance and better dispersion uniformity in the electrophoretic paint, and ensures the coating uniformity and good flatness of the paint forming. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the graphene complex powder comprising obtaining expanded graphite and graphite oxide, carrying out the first homogeneous operation to expanded graphite, obtain graphene homogeneous liquid, carrying out the second homogeneous operation to described graphite oxide to obtain graphene oxide homogeneous liquid, performing a mixing and coating operation on the graphene homogeneous liquid and the graphene oxide homogeneous liquid to obtain a coating liquid, under the condition of greater than 100℃, performing reduction spray drying operation on the coating liquid to obtain coated particles, under the atmosphere of ammonia plasma, carrying out the surface amination modification operation on the coated particles; electrophoretic paint, comprising the graphene complex powder
