The purpose of this paper is to propose a facile, green and low-cost approach of the preparation of superhydrophobic cotton textiles, which can be fabricated with fluorinated TiO sols via a sol-gel method. The coating was prepared with TiO sols catalyzed with acetic acid, then modified by poly(Hexafluorobutyl methacrylate) (PHFBMA) which was synthesized by free radical polymerization. The wettability, surface morphology and chemical composition of pristine and modified cotton fabrics were investigated. The modified fabric presents a high contact angle reached up to 152.5°. The successful incorporation of fluorinated TiO nanoparticles into cotton fabric was verified by the above measurements results. Additionally, the chemical stability of the coated fabric has been tested by immersing in different pH solutions and organic solvents, demonstrating the outstanding water repellency of the fabric. Furthermore, the treated cotton fabric shows excellent self-cleaning properties, which makes it an ideal material for large-scaled industrial applications in various conditions.
本文旨在提出一种简便、绿色、低成本的方法来制备超疏水棉纺织品，该方法可以通过溶胶-凝胶法用氟化 TiO 溶胶制备。该涂层是用乙酸催化的 TiO 溶胶制备的，然后用自由基聚合合成的聚（六氟丁基甲基丙烯酸酯）（PHFBMA）进行改性。研究了原始和改性棉织物的润湿性、表面形态和化学组成。改性织物的接触角高达 152.5°。通过上述测量结果验证了氟化物 TiO 纳米粒子成功地掺入棉织物中。此外，还通过将涂覆的织物浸入不同 pH 值的溶液和有机溶剂中测试了其化学稳定性，表明该织物具有优异的拒水性。此外，处理过的棉织物具有优异的自清洁性能，使其成为各种条件下大规模工业应用的理想材料。
