摘要:

石墨烯是目前厚度较薄,硬度和强度较高的一种新型二维层状结构的碳材料,具有优异的化学惰性、抗氧化能力和阻隔性能。针对石墨烯在海洋有机防腐涂层领域的应用,归纳了石墨烯的防腐机理,主要在于屏蔽作用、缓蚀作用、加固作用和阴极保护作用,指出了石墨烯在涂层应用中存在易团聚、难定向排列、自身结构有缺陷等问题,提出了相应的改进措施并评价了改善效果,最后展望了石墨烯防腐涂层在多功能化、智能化和绿色化的未来发展方向。

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
