摘要
将聚酯织物先后在水性聚氨酯胶黏剂溶液以及由乙烯基三乙氧基硅烷改性纳米二氧化硅、2-甲基丙烯酰氧乙基三甲基氯化铵、聚乙二醇二甲基丙烯酸酯、三羟甲基丙烷三丙烯酸酯和2-羟基-2-甲基苯丙酮组成的乙醇混合溶液中浸泡,再经紫外固化,得到基于聚酯织物的无机有机复合超亲水涂层。红外光谱、扫描电镜和接触角测试结果确认了织物表面超亲水涂层的形成,水滴在织物表面完全铺展的时间最短仅为301 ms。利用超亲水聚酯织物可以进行油水分离,其分离效率达99. 4%。在经过50次循环分离后,其分离效率仍可保持在98%以上。
Polyester fabric was successively immersed in aqueous polyurethane adhesive solution and the ethanol solution composed of nano silica modified by vinyl triethoxysilane, 2- methacryloyloxyethyl trimethyl ammonium chloride, polyethylene glycol dimethacrylate, trimethylolpropane triacrylate and 2-hydroxy-2-methylpropiophenone. After UV curing, the inorganic and organic composite superhydrophilic coating on polyester fabric was obtained. FT-IR, SEM and contact angle test confirmed the formation of the superhydrophilic coating on the surface of the fabric. The minimum time for water droplets to fully spread on the surface of the superhydrophilic polyester fabric was only 301 ms. The superhydrophilic polyester fabric could be used for oil-water separation. The separation efficiency reached 99.4% and maintained more than 98% even after 50 separation cycles.
