Abstract: | Based on a large number of literatures related to graphene-based organicanticorrosion coatings at home and abroad,this paper reviewed its synergistic research on dispersion,orientation and functionalization. The practical problems and doubts encounteredin the research and application of graphene in anti-corrosion field were discussed,i. e. the local corrosion acceleration phenomenon caused by the conductivity of graphene and corresponding solutions. The influence mechanism of the conductivity and orientation of graphene on thezinc-rich coatings were discussed. |
