Fluorinated polyhedral oligomeric silsesquioxane (F-POSS) has been widely used for preparing liquid-repellent coatings. It is usually pre-synthesized and dispersed in expensive fluoro-solvent (or fluorosurfactant solution) for dip coating. Since the melting temperature of F-POSS is not high (122–140 °C), its loss during use is inevitable. However, reports on the grafting of F-POSS on substrate are rare. In this work, we report the fabrication of superhydrophobic and oleophobic cotton fabrics through the silane coupling of (heptadecafluoro-1,1,2,2-tetradecyl) trimethoxysilane (FAS) and 3-mercaptopropyltriethoxysilane (MPTES) on cotton fiber and the subsequent UV-induced thiol-ene click reaction between octavinyloctasilasesquioxane (OVPOSS) and MPTES thiols (and 1H, 1H, 2H, 2H-perfluorododecyl-1-thiol, PFDT). The as-prepared FAS/SH-F-POSS cotton fabric showed superhydrophobicity and high oleophobicity, as well as good durability and self-healing ability. It can withstand at least 15 accelerated washing cycles, 2000 abrasion cycles over sandpaper, 10 cycles of O₂ plasma etching, acid/alkaline/salt solution corrosion, and 25 cycles of UV aging/moist erosion. Such a durable superhydrophobic and oleophobic cotton fabric is useful for functional clothing and textile products in various fields.

氟化多面体低聚倍半硅氧烷 (F-POSS) 已广泛用于制备拒液涂料。它通常预先合成并分散在昂贵的含氟溶剂（或含氟表面活性剂溶液）中，用于浸涂。由于 F-POSS 的熔化温度不高（122-140°C），其在使用过程中的损耗是不可避免的。然而，关于 F-POSS 在基材上接枝的报道很少。在这项工作中，我们报告了通过（十七氟-1,1,2,2-十四烷基）三甲氧基硅烷（FAS）和 3-巯基丙基三乙氧基硅烷（MPTES）在棉纤维上的硅烷偶联以及随后的紫外线制备超疏水和疏油棉织物- 八乙烯基八烯基硅倍半硅氧烷 (OVPOSS) 和 MPTES 硫醇（和 1H、1H、2H、2H-全氟十二烷基-1-硫醇、PFDT）之间诱导的硫醇-烯点击反应。所制备的 FAS/SH-F-POSS 棉织物表现出超疏水性和高疏油性，以及良好的耐久性和自愈能力。它可以承受至少 15 次加速洗涤循环、2000 次砂纸磨损循环、10 次 O 循环₂次等离子蚀刻，酸/碱/盐溶液腐蚀，以及 25 次紫外线老化/潮湿腐蚀循环。这种耐用的超疏水疏油棉织物可用于各种领域的功能性服装和纺织产品。
