Abstract:

Graphene is currently known as a new type of carbon materials with two-dimensional layered structure with thin thickness,high hardness and strength.It has excellent chemical inertness,antioxidant capacity and barrier performance.Aim-ing at the application of graphene in the field of marine organic anti-corrosion coatings,the anti-corrosion mechanism of grapheme was summarized,mainly including shielding,corrosion inhibition,reinforcement and cathodic protection.The problems of graphene in coating application,such as easy agglomeration,difficult alignment and defects in its structure were pointed out.The corresponding modification methods were proposed and the improvement effect had been evaluated.Finally,the development directions for anti-corrosive graphene coatings in multi-function,intelligent and environmental friendly were prospected.

Key words: graphene, anti-corrosion, coating, metal corrosion
