In this study, a superhydrophobic fabric was synthesized by modifying the fiber's surface with dopamine-containing hydroxyl functional groups. Furthermore, we introduced mercapto-based functional groups by the hydrolysis of mercaptopropylmethyldimethoxysilane (MPMDS) and finally grafted POSS and mercaptans using a thiol-ene click reaction. These processes generated a superhydrophobic fabric with a static contact and a sliding angle of 162° and 8°, respectively. The superhydrophobic fabric's compact and regular micro-nano rough structure based on POSS and mercaptans provides stable fastness and durability, as well as high resistance to organic solvents, acid-base environments, mechanical abrasion, UV rays, and washing. Moreover, it can be used for self-cleaning and oil-water separation, and it has a wide range of applications in the coating industry.
在本研究中，通过用含多巴胺的羟基官能团修饰纤维表面来合成超疏水织物。此外，我们通过巯基丙基甲基二甲氧基硅烷（MPMDS）水解引入巯基官能团，最后利用硫醇-烯点击反应接枝POSS和硫醇。这些过程产生了一种超疏水织物，其静态接触角和滑动角分别为162°和8°。基于POSS和硫醇的超疏水织物致密且规则的微纳粗糙结构提供了稳定的色牢度和耐久性，以及对有机溶剂、酸碱环境、机械磨损、紫外线和洗涤的高抗性。此外，它可用于自清洁和油水分离，并且在涂料行业有广泛的应用。
