支撑层改性薄膜复合纳滤膜制备的研究进展

Gongye shui chuli
纳滤膜是纳滤技术的关键，其性能提升对海水淡化、盐湖提锂及高盐废水处理等领域意义重大。聚酰胺薄膜复合纳滤（TFC）膜的性能不仅受分离层固有特性的影响，多孔支撑层的结构与化学性质也对其分离性能、抗污染性能及长期稳定性具有关键调控作用。系统阐述了支撑层的共混改性（引入有机聚合物、无机纳米材料）和表面改性（涂覆、真空过滤沉淀、原位生长等）方法，分析了改性后支撑层在亲水性、孔隙率及表面形貌等方面的变化，及其对界面聚合反应过程的调控、分离层性能、薄膜复合纳滤膜性能的影响规律。结合近年来支撑层改性纳滤膜聚酰胺层的研究，

基于两性离子的纳滤膜抗污染改性方法研究进展

Gongye shui chuli
纳滤膜对水中污染物的分离截留性能优异，膜污染控制和抗污染强化是该技术发展的研究热点。纳滤膜改性是强化纳滤膜抗污染性能的方法之一，基于两性离子材料的改性纳滤膜凭借两性离子材料静电作用与水分子结合的特性，在渗透性和抗污性方面表现优秀。系统综述了强化抗污染的两性离子纳滤膜的改性方法，包括涂覆法、接枝法、界面聚合法、自组装和共混掺杂法等，并阐释了各方法所制备纳滤膜的抗污效能和适用条件，最后对各改性方法做出了展望，以期为两性离子材料在纳滤膜改性和实际应用中的研究提供参考。
