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.
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.
