During the fabrication of thin film composite (TFC) membranes by interfacial polymerization (IP), the utilization of salt additives is one of the effective methods to regulate membrane properties and performance. Despite gradually receiving widespread attention for membrane preparation, the strategies, effects and underlying mechanisms of using salt additives have not yet been systematically summarized. This review for the first time provides an overview of various salt additives used to tailor properties and performance of TFC membranes for water treatment. By classifying salt additives into organic and inorganic salts, the roles of added salt additives in the IP process and the induced changes in membrane structure and properties are discussed in detail, and the different mechanisms of salt additives affecting membrane formation are summarized. Based on these mechanisms, the salt-based regulation strategies have shown great potential for improving the performance and application competitiveness of TFC membranes, including overcoming the trade-off relationship between water permeability and salt selectivity, tailoring membrane pore size distribution for precise solute-solute separation, and enhancing membrane antifouling performance. Finally, future research directions are suggested to focus on the long-term stability assessment of salt-modified membranes, the combined use of different salt additives, and the integration of salt regulation with other membrane design or modification strategies.
在界面聚合（IP）制备薄膜复合（TFC）膜的过程中，盐添加剂的使用是调节膜性能的有效方法之一。尽管在膜制备方面逐渐受到广泛关注，但盐添加剂的使用策略、效果和潜在机制尚未得到系统总结。本综述首次全面概述了用于调整水处理用 TFC 膜性能和性能的各种盐添加剂。通过将盐添加剂分类为有机盐和无机盐，详细讨论了添加盐添加剂在 IP 过程中的作用以及对膜结构和性能的诱导变化，并总结了盐添加剂影响膜形成的不同机制。基于这些机制，基于盐的调节策略已显示出改善 TFC 膜性能和应用竞争力的巨大潜力，包括克服水透过率和盐选择性之间的权衡关系、调整膜孔径分布以实现精确的溶质-溶质分离，以及增强膜抗污染性能。最后，建议未来的研究方向侧重于盐改性膜的长期稳定性评估、不同盐添加剂的联合使用，以及将盐调节与其他膜设计或改性策略相结合。
