Abstract

Superhydrophobic textiles have attracted great interest due to their special functions and wide applications. However, it is still a huge challenge to construct a durable superhydrophobic coating for large-scale applications due to the complicated process and high cost. In this work, a facile two-step method was developed to construct superhydrophobic cotton fabric with fluorine-free treatment. The cotton fabrics were treated with modified nano SiO2 to construct rough surfaces. Then, the silicone oil was introduced into the surface of the cotton fabric to form superhydrophobic cotton fabric. The results showed that the modified nano SiO2 and silicone oil were stably fixed on the fiber surface. The static water contact angle test showed that contact angle of the modified cotton fabric was 158°, indicating excellent superhydrophobic properties. Furthermore, the self-cleaning and anti-pollution test results showed that the superhydrophobic cotton fabric possessed good self-cleaning and antifouling performance. This superhydrophobic fabric avoids the use of fluoropolymers and reduces the harm to humans and environment, showing a wide range of applications.

利用硅油和无机纳米粒子制备超疏水棉织物

超疏水纺织品由于其特殊的功能和广泛的应用而引起人们的极大兴趣。然而，由于工艺复杂、成本高，构建一种适用于大规模应用的耐用超疏水涂层仍然是一个巨大的挑战。在这项工作中，开发了一种简单的两步法来构建无氟处理的超疏水棉织物。采用改性纳米SiO2对棉织物进行表面处理，形成粗糙表面。然后，将硅油引入棉织物表面，形成超疏水棉织物。结果表明，改性后的纳米SiO2和硅油能稳定地固定在纤维表面。静态水接触角测试表明，改性后的棉织物的接触角为158°，具有优异的超疏水性能。自清洁防污试验结果表明，该超疏水棉织物具有良好的自清洁防污性能。这种超疏水织物避免了使用含氟聚合物，减少了对人类和环境的危害，具有广泛的应用前景。
