摘要
本文通过LiF/HCl体系刻蚀和超声剥离得到高浓度单层Ti3C2 MXene分散液,并利用其表面丰富的-OH活性位点与正十八烷基三乙氧基硅烷(OTES)反应,使脂肪链接枝在二维材料表面,成功制备亲油型MXene.将亲油型Ti3C2 溶于熟桐油中,配置成一定比例的改性剂,并与生漆共混,得到分散均匀的复合涂料.通过FT-IR、SEM等手段对材料和复合涂层进行了表征,同时着重考察了涂层的耐腐蚀性能.结果表明,与天然生漆涂层相比,改性涂层的性能有明显提升,其中改性剂添加量为 3wt%时效果最佳,腐蚀速率下降了 2 个数量级.
Abstract
In this paper,the high concentration monolayer Ti3C2 MXene dispersion was obtained by etching and ultrasonic stripping in LiF/HCl system.The rich-OH active site on the surface of Ti3C2 MXene was used to react with n-octadecyl trethoxysilane(OTES),and the liphile MXene was successfully prepared.The oleophilic Ti3C2 was dissolved in cooked tung oil,and then mixed with raw lacquer to get uniformly dispersed composite coatings.The materials and composite coatings were characterized by FT-IR and SEM,and the corrosion resistance of the coatings was investigated.The results show that,compared with the natural raw lacquer coating,the performance of the modified coating is significantly improved,and the best effect is achieved when the modifier amount is 3wt%,and the corrosion rate decreases by 2 orders of magnitude.
