摘要：

近年来，聚酰胺复合膜凭借其优异的渗透选择性已被广泛用于水处理领域，但膜性能的进一步优化提升仍是相关研究人员关注的热点。对成品膜进行后处理是改善膜性能的方法之一，具有简单、有效与可控等技术特征。本文回顾了近些年有关聚酰胺复合膜后处理改性的相关研究，将现有的后处理过程划分为酸/碱水解、溶剂活化、加氯氧化和其他后处理方法四类技术方法，论述了膜性能改善效能与其内在作用机理，并对未来研究方向提出了建议。

In recent years, polyamide thin film composite (TFC) membranes have been widely used in the field of water treatment due to their excellent permeability and selectivity, but the further promotion of membrane performance is still a hotspot concerned by relevant researchers. Post-treatment of the formed membrane is one of the methods to improve the membrane performance, of which property is simple, effective and controllable. This article reviewed the relevant research on the post-treatment modification of polyamide TFC membranes in recent years, and divided the existing post-treatment methods into four technical approaches: acid/base hydrolysis, solvent activation, chlorination oxidation, and other solution treatments. In addition, the membrane performance improvement efficiency and mechanism were expounded. Finally, the future development direction of polyamide TFC membranes were prospected.
