The thin film composite (TFC) membrane prepared by interfacial polymerization (IP) on porous supports is currently one of the most efficient technologies for brackish water purification and seawater desalination, including reverse osmosis (RO), forward osmosis (FO), and nanofiltration (NF). Over the past decades, there have been intensive and continuous efforts in research of polyamide layers, while there is little information in the literature about the impact that physical-chemical properties and structure of support membranes have on the formation of composite membranes. This paper reviews the recent research progress of the supporting membrane, comprehensively summarizes the support role in polyamide formation, and provides good insight into TFC membrane research and development. In addition, we discuss several types of polymer supporting membranes and related modification methods to explore the appropriate supporting membrane for enhancing TFC membrane performance and extending the applications in the future.
通过界面聚合(IP)在多孔载体上制备的薄膜复合(TFC)膜是目前用于微咸水净化和海水淡化的最有效技术之一,包括反渗透(RO)、正向渗透(FO)和纳滤(NF)。在过去几十年中,人们对聚酰胺层进行了深入且持续的研究,但文献中关于支撑膜的物理化学性质和结构对复合膜形成的影响的信息却很少。本文综述了支撑膜的最新研究进展,全面总结了支撑膜在聚酰胺形成中的作用,并为TFC膜的研发提供了深刻见解。此外,我们还讨论了几种类型的聚合物支撑膜及相关改性方法,以探索合适的支撑膜,用于增强TFC膜性能并拓展其未来应用。
