摘要
单层无缺陷石墨烯具有优异的屏蔽性能,能阻隔氧气、水分子等腐蚀因子到达金属基体表面,被认为是已知最薄的腐蚀防护涂层。基于石墨烯在金属腐蚀防护领域巨大的应用潜力,本文从石墨烯薄膜防护涂层、石墨烯/有机防护涂层以及石墨烯-导电高分子/有机防护涂层等方面进行系统总结,重点围绕石墨烯薄膜存在的问题以及石墨烯在有机涂层中均匀分散等进行详细分析和介绍,同时对石墨烯基防腐涂料的未来发展进行了展望。
Defect-free monolayer graphene with excellent shielding performance is impermeable to O2 and H2O molecules,which can protect metal against corrosion and hence is considered to be the thinnest known coating for corrosion protection. Based on the great potential of graphene in the field of metal corrosion protection,this paper systematically summarizes the graphene anticorrosion films,graphene / organic anticorrosion coatings and graphene-conductive polymer / organic anticorrosion coatings. The existing problems of graphene anticorrosion films and well-dispersed graphene in polymer coatings are also discussed. Finally,the future development of graphene based anticorrosion coatings is prospected.
