摘要:
含油废水的大量产生造成严重的环境污染,实现含油废水的高效油水分离引起社会的广泛关注。超疏水材料作为一种新型材料,对水和油的润湿性相反,具有高效分离油水污染物的能力。基于聚二甲基硅氧烷(PDMS)改性的方法制备了多功能性的超疏水织布。在紫外光[365 nm,(5.0±0.6) mW·cm-2]条件下,将化学性质稳定、机械性能良好的PDMS接枝到P25型二氧化钛钠米颗粒(P25 NPs)上,制备了无机-有机结合的超疏水涂层,将制备的涂层用于织布改性。改性织布具有超疏水性,能有效地分离油水混合物,分离效率大于99%,表现出良好的分离性能。将改性织布经过100次砂纸摩擦,100 h高温(150 ℃)处理,100 h低温(-20 ℃)处理以及紫外光照射100 h后也依然表现出稳定的超疏水性及油水分离效率。

Abstract:
The large-scale generation of oily wastewater often leads to serious environmental pollution, and effective separation of oil and water in oil-water mixtures has attracted widespread attention.?As a new type of material, superhydrophobic materials have the ability to efficiently separate oil-water pollutants due to their opposite wetting properties towards water and oil. In this study, a multifunctional superhydrophobic fabric was prepared based on the modification of polydimethylsiloxane (PDMS). Under ultraviolet light (365 nm, 5.0 ±0.6 mW·cm-2) conditions, an inorganic-organic superhydrophobic coating was prepared by grafting PDMS with stable chemical properties and excellent mechanical properties onto P25 type titanium dioxide nanoparticles (P25 NPs). The prepared coating was then used for fabric modification, which endowed the fabric with superhydrophobic properties. The modified fabric could be used for the separation of oil-water mixture. The separation efficiency is higher than 99%, exhibiting excellent separation performance. The modified fabric still maintains stable superhydrophobicity and oil-water separation efficiency even after undergoing 100 cycles of sandpaper friction, 100 h of high-temperature treatment (150 ℃), 100 h of low-temperature treatment (- 20 ℃) and 100 h of ultraviolet light irradiation.
