摘要：
Compared with the common self-healing coating, the self-healing polymer/graphene composite coating has better self-repairing ability and anti-corrosion performance. This is attributed to the superior physical and chemical properties of graphene, which can be used as the energy conversion center, energy transfer medium or corrosion medium shield in coatings. And according to different healing mechanisms, graphene can play different roles. In this paper, the function of graphene in self-healing coating and the application status of self-healing polymer/graphene composite coating are discussed in detail. First, the function of graphene is introduced from the intrinsic and extrinsic self-healing mechanisms. Second, the optimization measures of graphene properties and self-healing polymer/graphene composite coatings are summarized. And for graphene, the effects of its structure, size, electrical conductivity and dispersion on the self-healing properties are analyzed in detail. Finally, the current application problems of self-healing polymer/graphene composite coatings are analyzed, and the future development direction of self-healing polymer/graphene composite coatings is discussed.
