| 中文摘要: |
| 石墨烯凭借其良好的力学性能、高的长径比以及优异的不可渗透性，在涂层防护领域得到了人们的广泛青睐。然而，由于石墨烯超高导电性引起的“腐蚀促进行为”，限制了其在防腐涂料领域的进一步发展。综述了石墨烯的腐蚀促进行为对涂层防腐性能的影响，以及解决石墨烯腐蚀促进行为的策略。首先，概述了石墨烯的结构特点及其在防腐涂料领域应用过程中存在“微电偶腐蚀”的问题;其次，从3个方面(改善涂层的屏蔽性能、增强涂层的力学性能、改善涂层的阴极保护作用)对石墨烯的防腐机理进行了阐述;最后，从石墨烯的导电性、电势以及氧还原催化活性等角度，对其腐蚀促进行为的机理进行了分析。针对石墨烯在防腐涂层领域应用过程中存在“微电偶腐蚀”的问题，重点归纳了石墨烯表面绝缘化，石墨烯面内掺杂N、B、F等原子、开发石墨烯富锌涂层，设计石墨烯基自修复功能涂层，以及寻找h-BN等类石墨烯结构的二维纳米材料等多种解决策略，并对以上所有解决策略的最新研究进展进行了全面的综述。最后，展望了石墨烯在防腐涂料领域的发展趋势及主要研究方向。 |

| Graphene has been widely used in the field of coating protection by virtue of its good mechanical properties, high aspect ratio and excellent impermeability. However, because of its high electrical conductivity, the “corrosion-promotion behaviour” of graphene has limited its further development in the field of anticorrosive coatings. In this review, the anticorrosive properties and corrosion-promotion behaviour of graphene in coatings with the solutions of corrosion-promotion behaviour were reviewed. Firstly, the structural characteristics of graphene and the “micro-galvanic corrosion” graphene in the field of anti- corrosion coatings were summarized. Secondly, the anti-corrosion mechanism of graphene was elaborated from three aspects of elevating the shielding property of the coating, enhancing the mechanical property of the coating, and improving the cathodic protection effect of the coating. And then, the corrosion promoting activity mechanism of graphene was analyzed from the perspectives of its electrical conductivity, potential and oxygen reduction catalytic activity. In order to solve the problem of “micro-galvanic corrosion” of graphene in the field of anticorrosive coating, many strategies have been summarized emphatically, including an insulation modification of graphene; the doping of graphene with N, B, and F atoms; the development of graphene zinc-rich coatings; the design of graphene-based self-healing coatings, and the exploration of H-BN and other graphene-like two-dimensional nanomaterials, and the latest research progress of all the above strategies was reviewed comprehensively. Finally, the development trend and main research direction of graphene in the field of anticorrosive coatings were prospected. |
