摘　　要：渗透汽化是一种具有能耗低、操作简便等优点的膜分离技术,目前传统聚合物渗透汽化膜在分离性能和稳定性等方面还有欠缺。金属有机框架(MOF)是由金属离子与有机配体以自组装形式组建而成的晶态多孔材料,具有独特的性质,如对目标分子的选择性吸附和分子筛分效应,近年来许多研究表明将MOF作为填料引入聚合物基质中构筑混合基质膜(MMMs)对其渗透汽化性能有很好的促进作用。本文从MOF的不同系列出发,讨论了适用于渗透汽化混合基质膜的MOF种类,分析了MOF-聚合物混合基质膜的制备方法与改性策略,综述了该类混合基质膜在渗透汽化方面(有机溶剂脱水、从稀溶液中回收有机物、有机混合物的分离)的应用进展,总结了用于渗透汽化的MOF-聚合物混合基质膜研究面临的挑战,并对其未来发展提出展望。Pervaporation is a membrane separation technology with the advantages of low energy consumption and easy operation.At present,the traditional polymer pervaporation membrane still lacks in separation performance and stability.Metal-organic framework(MOF)is a crystalline porous material formed by self-assembly of metal ions and organic ligands.It has unique properties such as selective adsorption of target molecules and molecular sieving effect.In recent years,many studies have shown that the introduction of MOF as a filler into the polymer matrix to construct mixed matrix membranes(MMMs)has a good effect on its pervaporation performance.Starting from different series of MOF,this paper discusses the types of MOF suitable for pervaporation mixed matrix membrane,analyzes the preparation methods and modification strategies of MOF-polymer mixed matrix membrane,and reviews the application progress of this kind of mixed matrix membrane in pervaporation(dehydration of organic solvent,recovery of organic matter from dilute solution,separation of organic mixture).The challenges in the research of MOF-polymer mixed matrix membrane for pervaporation are summarized,and its future development is prospected.
