摘　　要：薄膜复合(TFC)膜凭借其优异的渗透性及选择性常用于水处理过程中的脱盐环节。为解决TFC脱盐膜在贮存/运行过程中因干燥、酸/碱水解、高温破坏或氯氧化导致性能下降的问题,国内外众多学者相继开展了各类提高其稳定性的研究。本文以广泛应用的TFC纳滤/反渗透膜为参照,论述了TFC脱盐膜在上述四种特殊条件下的破坏机制,并归纳了相关的稳定性提升策略。通过系统地梳理耐干、耐酸/碱、耐高温和耐氯四类“特殊稳定型”TFC脱盐膜的最新研究进展,指出了目前存在破坏机制研究工作不够深入、对不同稳定性之间的影响关注不足等问题。最后,展望了未来在进一步研究膜材料失效机制的同时,要兼顾“特殊稳定型”TFC脱盐膜的脱盐效能和耐污染能力,并开展对多重稳定性的TFC脱盐膜材料的探索,以期为日后的相关研究工作提供参考。The thin film composite(TFC)membranes with excellent permeability and selectivity are commonly used for desalination in water treatment.To overcome the membrane performance deterioration because of drying,acid/base hydrolysis,high temperature damage and chlorine oxidation attack during the storage/operating process,numerous works focusing on stability improvement of TFC membranes have been reported.Referring to the most popular nanofiltration/reverse osmosis membranes,this review concluded the damage mechanism of polyamide TFC membranes in the drying process,acid/alkali solution,high temperature and active chlorine solution,and then the strategy of corresponding stability improvement is summarized.By systematically combing the latest research progress of four kinds of“special stable”TFC desalting membranes,i.e.,dry resistance,acid/alkali resistance,high temperature resistance and chlorine resistance,it is pointed out that the current research work had problems such as lack of in-depth research on the mechanism of destruction and insufficient attention to the influence between different stabilities.Finally,the research direction in the future is prospected.While further studying the failure mechanism of membrane materials,it should pay more attention to the desalination efficiency and anti-fouling capacity of TFC desalination membranes with special stability,and explore multi-stability TFC desalination membranes,so as to provide reference for future related research work.
