In various academic and industrial interests, graphene has achieved remarkable attention mainly by its distinctive chemical, mechanical, thermal, electrical and excellent anti-corrosion properties respectively, whereby the previous and ongoing researches have shown positive outcomes and its respective results achieved were at a satisfactory level. Over the last few years, the scope of the research on the applications of graphene based anti-corrosion has been intensely broadened and consists of two components, firstly pure graphene coatings and secondly graphene composite coatings. In the formulation of polymeric coatings, due to graphene and its derivatives having extraordinary lamellar structure, this material is highly suitable as anti-corrosive additives. Graphene creates pathways that are highly tortuous, thereby preventing the water and oxygen molecules to be diffused to the metal-based surface of materials, resulting in the protection of metal from oxidation and corrosion. Therefore, comprehensively reviewed in this article is the graphene-based coatings applications to metal anti-corrosion. First, the basic fundamentals of anti-corrosive coating technology will be discussed followed by and the current progress. Second, in detail, the preparation of graphene followed by pure graphene coatings methods respectively are illustrated. Third, the pure graphene coating in terms of corrosion resistance will be discussed, followed by detailed explanation on its existing problems and optimization respectively. Next, associated with graphene-based organic coatings, the graphene and graphene oxide dispersion and modification will be discussed, followed by the mechanism of barrier properties of graphene as well as the influence of the electrical conductivity. The anti-corrosion mechanism, optimization measures, corrosion resistance, and existing problems are summarized for the composite coatings fabricated using graphene. The challenges and future developments of anticorrosive graphene coatings are finally discussed and proposed, and their potential applications are discussed.

在各个学术界和工业界，石墨烯分别以其独特的化学，机械，热，电和优异的防腐性能而受到了广泛的关注，从而既往和正在进行的研究均显示出积极的成果，并且取得的成果令人满意。等级。在过去的几年中，基于石墨烯的防腐应用的研究范围已经得到了广泛的拓展，它由两个部分组成，首先是纯石墨烯涂层，其次是石墨烯复合涂层。在聚合物涂料的配方中，由于石墨烯及其衍生物具有非凡的层状结构，因此该材料非常适合用作防腐添加剂。石墨烯会产生高度曲折的路径，从而防止水和氧分子扩散到材料的金属基表面，从而保护金属免受氧化和腐蚀。因此，本文全面综述了石墨烯基涂料在金属防腐中的应用。首先，将讨论防腐涂层技术的基本原理，然后介绍其最新进展。其次，详细说明了石墨烯的制备方法，然后分别介绍了纯石墨烯的涂覆方法。第三，将讨论纯石墨烯涂层的耐蚀性，然后分别详细解释其存在的问题和优化方法。接下来，将讨论与石墨烯基有机涂料相关的石墨烯和氧化石墨烯的分散和改性，其次是石墨烯的阻隔性能机理以及电导率的影响。总结了使用石墨烯制备的复合涂层的防腐蚀机理，优化措施，耐腐蚀性以及存在的问题。最后讨论并提出了防腐石墨烯涂料的挑战和未来的发展，并讨论了其潜在的应用前景。
