A robust, self-healing superhydrophobic poly(ethylene terephthalate) (PET) fabric was fabricated by a convenient solution-dipping method using an easily available material system consisting of polydimethylsiloxane and octadecylamine (ODA). The surface roughness was formed by self-roughening of ODA coating on PET fibers without any lithography steps or adding any nanomaterials. The fabric coating was durable to withstand 120 cycles of laundry and 5000 cycles of abrasion without apparently changing the superhydrophobicity. More interestingly, the fabric can restore its super liquid-repellent property by 72 h at room temperature even after 20000 cycles of abrasion. Meanwhile, after being damaged chemically, the fabric can restore its superhydrophobicity automatically in 12 h at room temperature or by a short-time heating treatment. We envision that this simple but effective coating system may lead to the development of robust protective clothing for various applications.
通过一种简便的溶液浸渍法，使用由聚二甲基硅氧烷和十八烷基胺（ODA）组成的易于获得的材料体系，制备了一种坚固、自修复的超疏水聚对苯二甲酸乙二酯（PET）织物。PET纤维上ODA涂层的自粗糙化形成了表面粗糙度，无需任何光刻步骤或添加任何纳米材料。织物涂层耐用，可承受120次洗涤循环和5000次磨损循环，而超疏水性无明显变化。更有趣的是，即使经过20000次磨损循环，该织物在室温下72小时后仍能恢复其超疏水性能。同时，在受到化学损伤后，该织物在室温下12小时或通过短时间加热处理可自动恢复其超疏水性。我们设想，这种简单而有效的涂层体系可能会推动适用于各种应用的坚固防护服的发展。
