| 中文摘要: |
| 腐蚀问题会影响金属材料的安全性和耐久性，是造成工程装备和设施失效及破坏的主要原因，严重损害了经济发展和人身安全。涂层是最有效和经济的防腐措施，随着对涂层性能的要求越来越高，复合涂层材料受到科研工作者的广泛关注。石墨烯具有高导电率、高硬度和优异的阻隔性等性能，但同时具有疏水性和易团聚的特点。氧化石墨烯的结构与石墨烯相似，高长径比能够提供有效的阻隔性能，表面丰富的含氧基团为化学改性提供了反应位点，从而实现在基体中均匀分散的目的，是一种可用于增强涂层防腐能力的理想碳材料。首先介绍了氧化石墨烯的制备和化学改性方法，并且对比了不同化学改性方法的优缺点以及作用机制。然后分类阐述了氧化石墨烯复合防腐涂层的研究现状，探讨了氧化石墨烯含量、分散性和制备条件等因素对复合涂层的影响。最后从不同方面（制备工艺、分散技术、防腐机制和工程应用）分析了氧化石墨烯涂层存在的主要问题，并展望了氧化石墨烯涂层的发展方向。 |

| Corrosion problem can affect safety and durability of metal materials, hence it is the main cause of failure and destruction of engineering equipment and facilities, which has seriously damaged economic development and personal safety. The use of coatings is the most effective and cost-optimal way to prevent corrosion. As ever higher demands are made for coatings, composite coatings have aroused general concern of science researchers. Graphene has excellent properties such as high conductivity, high hardness and excellent barrier properties, but it also features in hydrophobicity and easy agglomeration. The structure of graphene oxide is similar to that of graphene. Its high aspect ratio can provide effective barrier properties and abundant oxygen-containing groups on the surface can provide reaction sites for further chemical modification to achieve uniform dispersion in substrate. Therefore, graphene oxide is an ideal carbon material which can be used to improve corrosion resistance of coatings. Preparation and chemical modification methods of graphene oxide were briefly introduced. Advantages and disadvantages as well as action mechanism of different chemical modification methods were compared. Then research status of graphene oxide composite anti-corrosive coatings was presented by category. Effects of graphene oxide content, dispersibility and preparation conditions on the composite coatings were discussed. Finally, major challenges of graphene oxide composite coatings were discussed in different aspects (preparation technology, dispersion technology, anticorrosive mechanism and engineering application), and development direction of graphene oxide coatings was also predicted. |
