▎ 摘　　要

NOVELTY - Edge functionalized graphene is claimed, where the carboxy group of the edge functionalized graphene is selectively modified at the edge of the fully structured graphene sheet layer. USE - The graphene is useful in anticorrosive coating (claimed). ADVANTAGE - The graphene has simple preparation method, overcomes difficult to deal with graphene, and excellent anti-corrosion effect, and avoids destruction of structure of graphene sheet. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing edge functionalized graphene comprising dispersing the graphene in chlorate, concentrated sulfuric acid with hydrogen peroxide mixed solution to obtain mixed solution, and then reacting to obtain edge functionalized graphene; (2) anticorrosive coating comprises edge functionalized graphene; and (3) preparing anticorrosive coating comprising adding edge functionalized graphene into dispersant and mechanically stirring for 1-24 hours to obtain edge functionalized graphene anticorrosive coating which is edge functionalized graphene monocomponent anticorrosive coating.
