Nanofiltration (NF) membranes have been widely used in various fields including water treatment and other separation processes, while conventional thin film composite (TFC) membranes with polyamide (PA) selective layers suffer the problems of fouling and chlorine intolerance. Due to the abundant hydrophilic hydroxyl groups and ester bonds free from chlorine attack, the TFC membranes composed of polyester (PE) or polyester-amide (PEA) selective layers have been proven to possess enhanced anti-fouling properties and superior chlorine resistance. In this review, the research progress of PE and PEA nanofiltration membranes is systematically summarized according to the variety of hydroxyl-containing monomers for membrane fabrication by the interfacial polymerization (IP) reaction. The synthesis strategies as well as the mechanisms for tailoring properties and performance of PE and PEA membranes are analyzed, and the membrane application advantages are demonstrated. Moreover, current challenges and future perspectives of the development of PE and PEA nanofiltration membranes are proposed. This review can offer guidance for designing high-performance PE and PEA membranes, thereby further promoting the efficacy of nanofiltration.
纳滤 (NF) 膜已广泛应用于水处理和其他分离过程等各个领域，而具有聚酰胺 (PA) 选择性层的传统薄膜复合 (TFC) 膜存在着易污染和不耐氯的问题。由于聚酯 (PE) 或聚酯酰胺 (PEA) 选择性层中含有丰富的亲水性羟基和酯键，不受氯的攻击，因此已证明由其组成的 TFC 膜具有增强的抗污染性能和优异的耐氯性。本综述根据用于界面聚合 (IP) 反应的含羟基单体的种类，系统地总结了 PE 和 PEA 纳滤膜的研究进展。分析了定制 PE 和 PEA 膜性能和性能的合成策略和机制，并展示了膜应用的优势。此外，还提出了开发 PE 和 PEA 纳滤膜的当前挑战和未来展望。本综述可为设计高性能 PE 和 PEA 膜提供指导，从而进一步提高纳滤的效果。
