【摘要】：石墨烯(类)材料作为明星材料,是诸多应用领域的研究热点。主要从两个方面综述了石墨烯材料在金属腐蚀防护中的应用研究现状,简要概述了单纯的石墨烯薄膜用于金属防护的发展历程,并对该防护手段的弊端进行了分析与讨论,得出石墨烯薄膜不适合直接覆于金属表面用于防腐蚀的结论。详细介绍了石墨烯复合防护涂层的制备方法与性能,针对将石墨烯类材料作为填料改性防护涂层的研究现状,概括了该防护手段的缺点与改进策略,即通过在氧化石墨烯表面进行分子(硅烷偶联剂、聚合物单体等)修饰和表面覆盖纳米粒子(纳米Si O2、Al2O3、Ti O2颗粒等),达到增强石墨烯材料与防护涂层之间的相容性的目的。在此基础上,提出了"主动防护"的概念,构想出一种以石墨烯材料为基础的新型缓蚀剂纳米存储器,同时提出石墨烯材料的深层防护机制仍亟待解决。最后,立足于整个石墨烯行业,从工业化应用的角度出发,对石墨烯防护技术进行了展望。
[Abstract]:As star materials, graphene is a hot topic in many application fields. The application and research status of graphene materials in metal corrosion protection are reviewed in this paper. The development of simple graphene films for metal protection is briefly summarized, and the disadvantages of this protection method are analyzed and discussed. It is concluded that graphene film is not suitable for corrosion prevention on metal surface. The preparation methods and properties of graphene composite protective coatings are introduced in detail. The shortcomings and improvement strategies of the protective coating modified by graphene materials as fillers are summarized. In other words, the compatibility between graphene materials and protective coatings can be enhanced by modifying the surface of graphene oxide with molecular (silane coupling agent, polymer monomer, etc.) and covering the surface with nano-particles (nano-SiO _ 2, Al _ 2O _ 3, TIO _ 2, etc.). On this basis, the concept of "active protection" is put forward, and a novel corrosion inhibitor nano-memory based on graphene material is proposed. At the same time, the deep protection mechanism of graphene material still needs to be solved. Finally, based on the whole graphene industry and from the point of view of industrial application, the technology of graphene protection is prospected.
