摘要：
Aiming at the poor durability of superhydrophobic material surfaces, a durable superhydrophobic coating on cotton fabrics has been fabricated by immersing the fabrics into a solution consisting of SiO2 particles modified by octadecylamine and dodecyltrimethoxyl, and polydimethylsilane. The chemical composition, surface morphology, contact angle, mechanical durability, chemical stability and oil-water separation performance of superhydrophobic cotton fabric were tested and characterized. The results show that when the addition of polydimethylsilane is 1.0 mL and the amount of modified SiO2 is 3.0 g, the obtained fabric exhibits excellent superhydrophobic property with a water contact angle of 164.5°. Superhydrophobic cotton fabric is proven to be resistant to mechanical abrasion and acidic and alkaline attacks. In addition, the practical application of the modified fabric for oil-water separation is also demonstrated with a high separation efficiency above 90%. The superhydrophobic cotton fabric developed in this research is strong, environmentally friendly, easy to manufacture, and has broad application prospects in the field of oil-water separation. © 2021, Periodical Agency of Journal of Textile Research.
