摘要:

界面聚合法制备的聚酰胺薄层复合膜凭借着渗透通量以及分离选择性高、化学稳定性佳等优点在水处理等领域有着广泛应用。聚酰胺分离层的物理结构和化学性质决定着复合膜的分离性能,通过调控界面聚合过程来优化聚酰胺层的理化性质可提高复合膜的分离性能。本文聚焦聚酰胺分离层性质与复合膜性能之间的关系,从基膜改性、调控单体反应过程、聚酰胺层后处理三个方面综述了近年来调控界面聚合制膜过程的研究进展。通过分析单体传质对界面聚合反应的影响以及膜结构与性能间的构-效关系,总结了界面聚合制备聚酰胺复合膜的调控机理和方法,为进一步提升聚酰胺复合膜的分离性能提供理论依据和发展方向。

Abstract:

Polyamide (PA) thin-film composite (TFC) membrane prepared via interfacial polymerization (IP) has been extensively used in water treatment due to its advantages of high permeability, high separation selectivity and good chemical stability. The separation performance of PA TFC membrane is mainly determined by the physical structure and chemical properties of the PA skin layer, which can be improved by regulating and optimizing the IP process. Hence, this review focused on the relationship between the physicochemical properties of the PA layer and the separation performance of the TFC membrane, and summarized the research progress on IP-based membrane preparation from three aspects: modification of membrane substrate, regulation of monomers reaction process and post-treatment of PA layer. By analyzing the influence of monomer mass transfer on the IP reaction as well as the relationship between membrane structure and performance, the regulation mechanisms and methods of the IP process to prepare PA TFC membranes were summarized, which provided fundamental theories and perspectives for further improvement of the separation performance of PA TFC membrane.

Key words: nanofiltration, reverse osmosis, membrane modification, membrane preparation, thin-film composite membrane
