There is provided a graphene-based coating suspension comprising a plurality of graphene sheets, a thin film coating of an anticorrosive pigment or sacrificial metal deposited on the graphene sheet, and a binder resin dissolved or dispersed in a liquid medium, wherein the plurality of graphene sheets Is essentially a single layer or a few layers of graphene sheets selected from pure graphene materials having 0% non-carbon elements, or non-pure graphene materials having 0.001 wt% to 47% by weight non-carbon elements. Containing, wherein the non-pure graphene is graphene oxide, reduced graphene oxide, graphene fluoride, chlorinated graphene, brominated graphene, iodide graphene, hydrogenated graphene, nitrogenated graphene, doped graphene , Chemically functionalized graphene, or a combination thereof. The present disclosure also provides a method of making such a coating suspension. Also provided is an object or structure, at least partially coated with such a coating. |
