石墨烯具有极好的阻隔性能、屏蔽性能及化学稳定性，其在防腐防污涂料中的应用已经被深入研究。介绍了石墨烯对防腐防污涂层性能的影响：降低水、氧气等腐蚀介质的渗透率，加强抗生物附着性，抑制微生物腐蚀。分析了石墨烯在涂料中的应用缺陷及产生原因：极强的范德华力导致石墨烯在涂料中分散性差、易团聚，高化学稳定性及疏水性导致石墨烯与成膜物质结合性差，超高的导电性导致石墨烯膜在失效时加速金属腐蚀。综述了为应对石墨烯在防腐防污涂料中的应用缺陷，国内外学者采用的主要方法：采用改性处理方法制备改性石墨烯（GO、RGO、FG）以及合成石墨烯复合颗粒（石墨烯修饰纳米粒子，即GO-Al2O3颗粒、GO-TiO2颗粒、GO-SiO2颗粒等；树脂负载石墨烯复合填料，即石墨烯/聚苯胺复合填料等）。最后展望了石墨烯及其衍生物在防腐防污涂料中的发展。

Graphene has excellent barrier, shielding and chemical stability, the application of graphene in anti-corrosion and anti-fouling coatings has been deeply studied. Studies have shown that adding a certain amount of graphene to traditional coatings can significantly reduce the permeability to corrosive media such as water, oxygen, etc., and can enhance the bioadhesion of coatings and inhibit microbial corrosion. However, some disadvantages also appear in applications of graphene. For example, the strong van der Waals force between graphene lamellae leads to poor agglomeration and dispersion of graphene in coatings; the high chemical stability and hydrophobicity of graphene lead to poor adhesion between graphene and film-forming materials; and the superconductivity of graphene leads to the acceleration of metal corrosion when graphene film fails. In order to diminish the disadvantages of graphene during application, many methods have been explored, in which modified graphene (GO, RGO, FG) and synthetic graphene composite particles (graphene modified nanoparticles: GO-Al2O3 particles, GO-TiO2 particles, GO-SiO2 particles, etc.; resin-supported graphene composite filler: graphene/polyaniline composite filler, etc.) are main methods. Finally, the development of graphene and its derivatives in anticorrosive and antifouling coatings is prospected.
