| Abstract: |
| In recent years, graphene nanocomposites have attracted great attention in corrosion protection because of their excellent physical barrier, chemical stability, electrical conductivity and mechanical property. Reviews the application and research progress of graphene in the field of organic anticorrosive coatings. Firstly, it analyzes the application of graphene in the field of coatings by focusing on the necessary conditions for corrosion resistance and service life of anticorrosive coatings, basing on the four important factors determining the corrosion resistance of anticorrosive coatings, such as physical shielding property, self-repairability, adhesion and cathodic protection effect, and combining the lamellar shielding effect, multi-active sites, bonding strength with substrate and electrical conductivity of graphene/graphene oxide. Secondly, in view of the poor dispersity of graphene in coatings, summarizes the research progress of various dispersion modes and compares their advantages and disadvantages. Furthermore, it proposes that the ordered arrangement of graphene is a method to further improve the shielding property of the coatings on the basis of full dispersion and that the premise of giving full play to the shielding property is that the graphene material is distributed in the direction parallel to the substrate, in other words, the perpendicular or random distribution of graphene/graphene derivatives cannot ensure the structural compactness of the coatings, which is contrary to the shielding property. Additionally, in view of the galvanic corrosion of graphene in the coatings, by combining the dispersity of graphene, discusses and summarizes the research law of the amount of graphene used in the coatings and suggests that the galvanic corrosion could be reduced and eliminated by insulating graphene and introducing self-repairing groups. Finally, it further summarizes and analyzes the development trend of graphene in the field of corrosion protection in the future and relevant research suggestions from the aspects of dispersion stability, electrochemical anticorrosion, environmental protection, and economy. |
