| 中文摘要: |
| 石墨烯凭借其优异的物理阻隔性、化学稳定性、导电性以及良好的力学性能等综合性能，成为防腐涂料领域的研究热点。综述了石墨烯在有机防腐涂层领域的应用研究进展。首先，围绕防腐涂料耐蚀性能和使用寿命的必要条件，从涂层的物理屏蔽性、自修复性、附着力以及阴极保护功效四个决定涂料耐蚀性的重要因素入手，结合石墨烯/氧化石墨烯相匹配的片层屏蔽效应、多活性位点、与基材的结合强度以及导电性等优异特性，对石墨烯在涂层中的作用进行分析。其次，针对石墨烯在涂层应用中所面临的分散性差的问题，对多种分散方式下的研究进展进行了总结，比较了不同分散方式的优缺点。同时，提出石墨烯的有序排列是在充分分散的基础上，进一步提高涂层屏蔽性的方法，发挥其屏蔽性的前提是石墨烯材料呈平行于基材的方向分布，因为垂直或者呈杂乱方向分布的石墨烯/石墨烯衍生物无法满足涂层的结构致密性需求，有悖于屏蔽理念。另外，针对石墨烯在涂层应用中所面临的电偶腐蚀问题，结合石墨烯的分散性，探讨并总结了关于石墨烯在涂料体系中的用量规律，并提出可通过石墨烯的绝缘化以及引入自修复基团来减弱和消除电偶腐蚀效应的建议。最后，从分散稳定性、电化学防腐性、环保性、经济性等方面，进一步总结分析了未来石墨烯在防腐蚀领域中的发展趋势及研究建议。 |

| In recent years, graphene nanocomposites have attracted great attention in corrosion protection because of their excellent physical barrier, chemical stability, electrical conductivity and mechanical property. Reviews the application and research progress of graphene in the field of organic anticorrosive coatings. Firstly, it analyzes the application of graphene in the field of coatings by focusing on the necessary conditions for corrosion resistance and service life of anticorrosive coatings, basing on the four important factors determining the corrosion resistance of anticorrosive coatings, such as physical shielding property, self-repairability, adhesion and cathodic protection effect, and combining the lamellar shielding effect, multi-active sites, bonding strength with substrate and electrical conductivity of graphene/graphene oxide. Secondly, in view of the poor dispersity of graphene in coatings, summarizes the research progress of various dispersion modes and compares their advantages and disadvantages. Furthermore, it proposes that the ordered arrangement of graphene is a method to further improve the shielding property of the coatings on the basis of full dispersion and that the premise of giving full play to the shielding property is that the graphene material is distributed in the direction parallel to the substrate, in other words, the perpendicular or random distribution of graphene/graphene derivatives cannot ensure the structural compactness of the coatings, which is contrary to the shielding property. Additionally, in view of the galvanic corrosion of graphene in the coatings, by combining the dispersity of graphene, discusses and summarizes the research law of the amount of graphene used in the coatings and suggests that the galvanic corrosion could be reduced and eliminated by insulating graphene and introducing self-repairing groups. Finally, it further summarizes and analyzes the development trend of graphene in the field of corrosion protection in the future and relevant research suggestions from the aspects of dispersion stability, electrochemical anticorrosion, environmental protection, and economy. |
