In this article, the applications and modification methods of graphene-based materials [graphene and graphene oxide (GO)] in an organic anticorrosive coating were reviewed. First, this paper introduces the application of graphene-based materials with barrier property and electrical conductivity in anticorrosive coating and then explains the protection mechanisms, respectively. In addition, this paper puts forward some problems of graphene in the anticorrosive coatings, such as how to solve the dispersion of graphene, how to improve the compatibility between graphene and the polymer matrix, and how to enhance the adhesion between the coating and metal interface. Second, this paper summarizes the reported modification methods of graphene and GO in terms of covalent and noncovalent modification. For covalent modification, the modification methods of different functional groups of GO are summarized, such as modification of epoxy group (–C(O)C–), hydroxyl group (–OH), and carboxyl group (–COOH). As for the noncovalent modification, the modification methods of graphene and GO are summarized from the three aspects of π−π interaction, hydrogen bond interaction, and electrostatic interaction, respectively. Finally, the applications of graphene-based materials in anticorrosive coatings are summarized and prospected.
