Claim 10:
11. An object or structure coated at least in part with a coating comprising multiple graphene sheets, thin coating of an anti-corrosive pigment or sacrificial metal deposited on graphene surfaces, and a binder resin that bonds said coated graphene sheets together and to a surface of said object or structure, wherein said multiple graphene sheets contain single-layer or few-layer graphene sheets selected from a pristine graphene material having essentially zero % of non-carbon elements, or a non-pristine graphene material having 0.001% to 47% by weight of non-carbon elements wherein said non-pristine graphene is selected from graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination thereof and wherein said graphene sheets have a weight fraction from 0.1% to 30% based on the total coating weight, wherein said anti-corrosive pigment or sacrificial metal is selected from zinc phosphate; and wherein said binder resin contains a resin selected from polyimide, thermoset polyester, vinyl ester resin, silicate adhesive, or a combination thereof.
