摘要:

采用溶胶-凝胶法制得ZnO溶胶, 以棉织物为基底, 在其表面浸涂ZnO溶胶, 再经辛基三甲氧基硅烷表面修饰后显示出超疏水性和超亲油性, 水滴和油滴在其表面的接触角分别为152°和0°. 利用棉织物表面的超疏水性和超亲油性, 可以实现对油水混合物中油和水的有效分离. 为防水服饰的设计、 超疏水/超亲油材料的制备及在油水混合物的分离与应用提供借鉴.

Abstract:

ZnO colloids were firstly prepared by sol-gel method, and then, cotton fabric with superhydrophobicity and superoleophilicity was fabricated by dipping-coating ZnO colloids and subsequently modifying the surface with octyltrimethoxysilane, contact angles of water and oil droplet on the surface was about 152° and 0°, respectively. The cotton fabric with superhydrophobicity and superoleophilicity can be applied to separate oil or water from water-oil mixtures with high efficiency. The research are expected to offer references for the design of waterproof clothing, fabrication of superhydrophobic-superoleophilic material and its application in the separation of oil-water mixtures.

Key words: Superhydrophobic, Superoleophilic, Cotton fabric, ZnO colloid, Oil-water separation
