Superhydrophobic cotton fabric was fabricated by grafting aminopropyllsobutyl polyhedral oligomeric silsesquioxane (NH2-POSS) at room temperature using a tannic acid inspired surface modification method. The impact of the NH2-POSS concentration on the hydrophobicity of the fabric was investigated. The obtained superhydrophobic fabric exhibited an outstanding self-cleaning ability and excellent durability by resisting corrosive liquids, sandpaper abrasion for15 cycles, adhesive tape peeling for 50 cycles, ultrasonic treatment for 60 min, and high temperature of 200 °C. Furthermore, the superhydrophobic fabric could be utilized as a promising filter screen for separating oils from water with ultrahigh flux (∼19,600 L m−2 h−1) and separation efficiency (to 99.91%) even after 30 separation cycles. This method is simple, environmentally friendly, economical and practical. It can be used to produce superhydrophobic material on a large scale, which indicates its great potential in the field of oil-water separation.

单宁酸/多面体低聚倍半硅氧烷涂层的超疏水棉织物,可有效分离油/水

超疏水性棉织物是通过在室温下使用鞣酸激发的表面改性方法接枝氨基丙基异丁基多面体低聚倍半硅氧烷(NH 2 -POSS)制成的。研究了NH 2 -POSS浓度对织物疏水性的影响。所获得的超疏水性织物通过抵抗腐蚀性液体,砂纸磨损15次循环,胶带剥离50次循环,超声处理60分钟以及200°C的高温表现出优异的自洁能力和出色的耐久性。此外,超疏水性织物可用作有前途的滤网,用于以超高通量(〜19,600 L m -2  h -1)和30分离周期后的分离效率(至99.91%)。该方法简单,环保,经济实用。可用于大规模生产超疏水材料,这表明其在油水分离领域的巨大潜力。
