超疏水性织物的制备及其在油品回收领域的潜能

Preparation of superhydrophobic fabric and the potential application in oil reclaim

超疏水性材料因其广阔的应用前景而备受瞩目。本研究采用一种简单可行、成本低廉的方式,同时赋予织物超疏水性能、热稳定性能及抗紫外线性能。结果表明,处理后的织物表面与水的接触角可达(151.5±2)o,紫外光透过率低于2%。经热重分析仪分析发现,该织物的热稳定性能亦得到明显提升。值得注意的是,该织物在油品回收领域展现了十分突出的潜能,可以有效地从水油污物中回收油品。

The construction of waterproof materials is of great technological importance in various applications. The major challenge is the scalable fabrication of the superhydrophobic materials with the desirable combination of a good thermal stability and the excellent ultraviolet-visible（UV） resistance. Here a simple, easily operating and low-cost approach for the textile with these functions is reported.After the decoration, the superhydrophobic textiles with the water contact angle（WCA） of 151.5° exhibit not only an efficient shielding property against the UV with transmittance less than 2%, but also an excellent thermal stability. More importantly, this fabric displays an outstanding potential applications in the oil reclaim, which can recycle the oil from the waste water with oil stain efficiently.
