Superamphiphobic coatings/materials are important for a wide variety of applications, but the majority of these coatings/materials still suffer from poor durability. Therefore, multifunctional superamphiphobic coatings/materials with strong mechanical and chemical stability are highly desired. Herein, a simple and flexible approach to produce multifunctional superamphiphobic poly(ethylene terephthalate) (PET) textiles was reported. First, dual micro/nanostructures on the PET fabric surface are constructed by hydrolysis of trimethoxymethylsilane, N-octyltriethoxysilane, and trimethylchlorosilane, and further modified by 1H,1H,2H,2H-perfluorodecyltriethoxysilane and poly(vinylidene fluoride). The as-obtained superamphiphobic PET fabrics show high liquid repellency to water, oil, organic liquids, and strong acid or alkali solutions, exhibiting a water contact angle (WCA) of 161° and an oil contact angle (OCA) of 156°. Meanwhile, the superamphiphobic PET fabrics show strong abrasion resistance; even after 180-cm consistent abrasion, the WCA still maintains 148° and the OCA maintains 140°. Importantly, the fabrics maintain their excellent superamphiphobic property after long-term UV irradiation or ultrasonic treatment, respectively. Because the prepared fabrics have multifunctional features and are easy to fabricate with low cost, they show great potential for self-cleaning, antifouling, anti-icing, drug reduction, corrosion resistance, and protective uniforms.

轻松制造耐用的超疏水性PET织物

超疏水涂层/材料对于广泛的应用很重要，但是这些涂层/材料中的大多数仍然具有较差的耐久性。因此，非常需要具有强机械和化学稳定性的多功能超两性涂层/材料。在本文中，报道了一种简单且灵活的方法来生产多功能超疏水性聚对苯二甲酸乙二醇酯（PET）纺织品。首先，通过三甲氧基甲基硅烷，N-辛基三乙氧基硅烷和三甲基氯硅烷的水解来构建PET织物表面上的双重微/纳米结构，并进一步进行1 H，1 H，2 H，2 H改性-全氟癸基三乙氧基硅烷和聚偏二氟乙烯。如此获得的超疏水性PET织物对水，油，有机液体和强酸或强碱溶液表现出高拒液性，水接触角（WCA）为161°，油接触角（OCA）为156°。同时，超疏水性的​​涤纶织物具有很强的耐磨性。即使经过180厘米的持续磨损，WCA仍保持148°，OCA保持140°。重要的是，该织物在长期的紫外线照射或超声处理后分别保持其优异的超疏水性。由于制备的织物具有多功能特性，并且易于以低成本制造，因此它们显示出自清洁，防污，防冰，减少毒品，耐腐蚀和防护服的巨大潜力。
