石墨烯改性有机防腐涂料研究进展

Research Progress of Graphene Modified Organic Anticorrosive Coatings

综述了石墨烯及氧化石墨烯在改性有机防腐涂料领域的研究现状。主要介绍了石墨烯及氧化石墨烯的改性和分散、石墨烯的功能集成及其在有机防腐涂料中的应用以及石墨烯和氧化石墨烯导电性对于有机防腐涂料的影响。目前，石墨烯有机防腐涂层在工业应用中的最大困难之一是赋予石墨烯有机防腐涂层主动保护功能。如果在工艺创新和工艺改进后，负载在石墨烯表面的纳米氧化物层增加到亚微米厚度，并具有粗孔隙率和强结合强度的特性，纳米氧化物／石墨烯复合材料改性的有机防腐涂料将同时具备优异物理屏障性能和主动防护性能。

The research progress of graphene and graphene oxide in modified organic anticorrosive coatings is reviewed. The modification and dispersion of graphene and graphene oxide, functional integration of graphene and its application in organic anticorrosive coatings, and the influence of conductivity of graphene and graphene oxide on organic anticorrosive coatings are mainly introduced. At present, one of the greatest difficulties in the application of graphene modified organic anticorrosive coating in industrial applications is how to enable the graphene modified organic anti-corrosion coating an active protection function. If the thickness of the nano-oxides layer loaded on the surface of graphene is increased up to submicron level and it has the characteristics of coarse porosity and strong bonding strength, the organic anticorrosive coatings modified by nano-oxides/graphene composite will have the properties of the barrier properties and active protection.
