摘要

基于巯基烯的点击化学反应，成功将γ-巯丙基三乙氧基硅烷（KH-580）与乙烯基封端的聚二甲基硅氧烷（vinyl-PDMS）接枝到织物上，制备出具有优异油水分离效果的超疏水织物。利用红外光谱、扫描电子显微镜、X-射线光电子能谱等对改性织物进行表征，并考察了其表面疏水性及油水分离性能。结果表明，得到的超疏水织物表面具有沟壑和条纹结构，接触角最高可达156°，滚动角最高可达2°。超疏水织物的油水分离效率最高为99.8%，并且在连续进行20次油水分离之后，依然保持99%的分离效率。

Abstract

γ-Mercaptopropyltriethoxysilane (KH-580) and vinyl-terminated polydimethylsiloxane (vinyl-PDMS) were successfully grafted onto the fabric via thiol-ene click reaction

thus

super hydrophobic fabric with excellent oil-water separation ability prepared. The modified fabrics were characterized by infrared spectroscopy

scanning electron microscopy and X-ray photoelectron spectroscopy. The surface hydrophobicity and oil-water separation performance were investigated and their results showd that the surface of the superhydrophobic fabric obtained was in gully and stripe structure with a contact angle of 156° and a rolling angle of 2°. 99.8% of the oil-water mixture could be separated by the fabric

and the ratio stayed around 99% after 20 cycles.
