通过在环己烷/庚烷混合溶剂中于80 °C溶胀聚丙烯（PP）织物，开发了一种简单、快速（10 s）且可规模化制备超疏水PP织物的方法。溶胀大分子在纤维表面发生重结晶，形成亚微米突起，显著增加纤维表面的粗糙度，从而产生超疏水行为。超疏水PP织物对血液、尿液、牛奶、咖啡和其他常见液体具有优异的排斥性，并且显示出良好的耐久性和鲁棒性，例如对水渗透、磨损、酸/碱溶液和沸水的显著抵抗性。超疏水PP织物优异的综合性能预示着其作为油水分离材料、防护服、尿布垫等医疗卫生用品的潜在应用前景。这种简单、快速和低成本的方法在相对低的温度下操作，就考虑大规模制造而言，上级用于制造超疏水PP材料的其他报道的技术。此外，该方法也适用于制备超疏水聚丙烯薄膜和片材。
A simple, rapid (10 s) and scalable method to fabricate superhydrophobic polypropylene (PP) fabrics is developed by swelling the fabrics in cyclohexane/heptane mixture at 80 °C. The recrystallization of the swollen macromolecules on the fiber surface contributes to the formation of submicron protuberances, which increase the surface roughness dramatically and result in superhydrophobic behavior. The superhydrophobic PP fabrics possess excellent repellency to blood, urine, milk, coffee, and other common liquids, and show good durability and robustness, such as remarkable resistances to water penetration, abrasion, acidic/alkaline solution, and boiling water. The excellent comprehensive performance of the superhydrophobic PP fabrics indicates their potential applications as oil/water separation materials, protective garments, diaper pads, or other medical and health supplies. This simple, fast and low cost method operating at a relatively low temperature is superior to other reported techniques for fabricating superhydrophobic PP materials as far as large scale manufacturing is considered. Moreover, the proposed method is applicable for preparing superhydrophobic PP films and sheets as well.
