摘要

摘要本研究采用贻贝仿生技术,在多孔聚偏氟乙烯(PVDF)基底膜上构建了一种新型的“三层三明治”复合疏松纳滤膜结构,以贻贝仿生涂层为中间层,多酚和金属离子的复杂网络为顶层。新型复合纳滤膜具有分离性能好、亲水性好、防污能力强等综合性能。实验结果表明,单宁酸(TA)和铁离子(Fe3+)的结合可以显著提高复合纳滤膜的综合性能,水通量超过3000 L/(m2∙h),染料和牛血清蛋白(BSA)的保留率超过90 %, 接触角可达30°。TA与铜离子(Cu2+)的结合可以大大提高亚甲蓝的防污性能和截留能力。金属离子与多酚的络合活性与金属离子的氧化作用有关。PVDF/DA-PEI/TA-M+“三层夹心”纳滤膜复合结构方案为开发综合性能优异的新型纳滤膜提供了新思路和未来发展方向。

Preparation and performance of “three-layer sandwich” composite loose nanofiltration membrane based on mussel bionic technology
Abstract In this study, a novel “three-layer sandwich” composite loose nanofiltration (NF) membrane structure by mussel bionic technology was constructed on a porous polyvinylidene fluoride (PVDF) substrate membrane, with a mussel bionic coating as the middle layer and the complex network of polyphenols and metal ions as the top layer. The new composite NF membrane had comprehensive properties such as excellent separation performance, good hydrophilicity and strong antifouling ability. The experimental results showed that the combination of tannic acid (TA) and iron ion (Fe3+) could significantly improve the comprehensive performance of the composite NF membrane, with water flux of more than 3000 L/(m2∙h), and the retention rate of dyes and bovine serum protein (BSA) exceeded 90 %, and contact angle was up to 30°. The combination of TA and copper ion (Cu2+) can greatly enhance the antifouling performance and interception ability of methylene blue. The complexation activity of metal ions and polyphenols was related to the oxidation of metal ions. The PVDF/DA-PEI/TA-M+ composite structure scheme of “three-layer sandwich” NF membrane provides a new idea and future development direction for the development of novel NF membranes with excellent comprehensive performance.
