【摘要】：石墨烯是一种新型二维层状结构的碳材料,具有高长径比及优异的疏水、导电、导热和化学稳定性能,使其在防腐涂料中具有广泛的应用前景。涂覆有机涂层具有施工简单、价格低廉、应用范围广和防护性能好等其它防护措施无法比拟的优点,是一种减缓金属腐蚀有效、经济的手段。有机涂层中添加一定量的功能颜填料,可明显增加涂层的致密性或拉伸强度,进而提高涂层对基底金属的防护性能。综述了石墨烯涂层和石墨烯复合涂层对金属防护性能的研究进展,重点探讨两种涂层体系的防护机理和失效衍化机制,总结分析石墨烯分散性能和石墨烯基涂层制备技术与其防护性能的构效关系,并指出石墨烯作为高性能防护材料仍需解决的问题及未来研究方向。
[Abstract]:Graphene is a new two-dimensional layered carbon material with high aspect ratio, excellent hydrophobic, conductive, thermal conductivity and chemical stability, which makes it widely used in anticorrosive coatings. The coated organic coating has the advantages of simple construction, low price, wide application range and good protective performance, etc. It is an effective and economical means to slow metal corrosion. Adding a certain amount of functional pigments and fillers into organic coatings can obviously increase the densification and tensile strength of the coatings and then improve the protective properties of the coatings on the substrate metal. The research progress of graphene coating and graphene composite coating on metal protection is reviewed, and the protective mechanism and failure evolution mechanism of the two coating systems are mainly discussed. This paper summarizes and analyzes the structure-activity relationship between graphene dispersibility and graphene based coating preparation technology and its protective properties, and points out the problems that still need to be solved and the future research direction of graphene as a high performance protective material.
