摘　　要：采用TiO2溶胶处理棉织物,然后分别使用硬脂酸,1H,1H,2H,2H全-氟十二烷基三氯硅烷,以及两者联合对织物表面进行低表面能处理,制备超疏水棉织物。采用扫描电子显微镜观察织物表面形貌,研究了织物表面的润湿性能,并测试织物的紫外线透过率。结果表明,TiO2的引入不仅使微米级纤维表面粗糙化,从而获得微纳粗糙结构织物表面,增强织物疏水性能,还可以使织物具有良好的紫外线屏蔽性能。当TiO2的质量分数为0.8%时,紫外线防护性能达到最佳。Superhydrophobic cotton fabric was prepared by TiO2 sol coating followed by low surface energy treatment with stearic acid, 1H, 1H,2H,2H-perfluorodecyltrichlorosilane and their combination respectively. Surface wettability, surface morphology and transmission of UV ray of the finished cotton were tested. It was found that introduction of TiO2 nano particles not only facilitated the generation of a dual-size roughness on the substrate, favoring superhydrophobicity of the fabric, but also imparted cotton fabric excellent UV-shielding property. Optimal UV-shielding property was achieved when dosage of TiO2 was 8%.
