摘要：

为提高超疏水织物的耐久性,采用强黏附性物质茶多酚(Tps)、十六烷基三甲氧基硅烷(HDS)和七水合硫酸亚铁对涤纶织物进行整理,并对整理织物的表面形貌、化学组成、超疏水稳定性和油水分离性能进行测试与表征。结果表明:当茶多酚质量浓度为2 g/L,十六烷基三甲氧基硅烷用量为150 μL/L,七水合硫酸亚铁质量浓度为6 g/L时,整理织物表现出良好的超疏水性,静态水接触角达到163.1°,滚动角达到3.5°,其在水洗、机械磨损、紫外线辐照、模拟海水、酸碱环境及有机试剂浸泡等条件下均表现出良好的稳定性;在油水分离多次循环测试中,分离效率保持在95%以上。超疏水涤纶织物制备过程简单,稳定性良好,在油水分离领域具有广阔的应用前景。

Abstract:

In order to improve the durability of superhydrophobic fabrics, a polyester (PET) fabric was treated with strong adhesion substances including tea polyphenols (Tps), Hexadecyltrimethoxysilane (HDS) and FeSO₄·7H₂O. Surface morphology, chemical composition, superhydrophobic stability and oil-water separation performance of the prepared PET fabric were tested and characterized. The results show that when Tps is 2 g/L, HDS is 150 μL/L and FeSO₄·7H₂O is 6 g/L, the prepared PET fabric showed good superhydrophobic property with water contact angle of 163.1° and the scrolling angle of 3.5°. The treated fabric shows good stability under the conditions of water washing, mechanical wear, mechanical friction, UV irradiation, simulated seawater, acid-alkaline and organic reagents. In the cyclic test for oil-water separation, the separation efficiency remains above 95%. The preparation process of superhydrophobic PET fabric is simple and has good stability, which has broad application prospects in the field of oil-water separation.

Key words: polyester fabric, tea polyphenols, superhydrophobic property, hexadecyltrimethoxysilane, oil-water separation
