摘要

金属-有机骨架(MOFs)膜具有孔道尺寸、结构易调控且可功能化等显著优点,在气体和液体膜分离领域呈现出巨大的发展潜力和研究价值。连续致密无缺陷MOFs膜的大面积制备是目前MOFs膜在分离领域应用面临的主要挑战之一,解决该问题的关键在于改善基膜和MOFs膜间的界面结合以及提高MOFs膜致密性。从化学修饰基膜、物理修饰基膜、MOFs晶种修饰基膜、二维材料诱导MOFs膜生长等4个方面入手,介绍MOFs膜的制备方法及其在膜分离领域的研究进展,重点阐释了不同修饰和制膜方法的机理,分析了其对成膜性和膜分离性能的影响规律,总结了MOFs膜制备研究中存在的问题,并对MOFs膜制备的发展方向进行了展望。

Abstract

Metal-organic framework(MOF) membranes,featured by designable and tunable pore sizes,structures,easy functionalization and so on,have great potential and research value in the field of gas or liquid separation.Preparation of continuous dense and defect free MOFs membrane with large area is one of the main challenges for the application of MOFs membrane in separation field.The key to solve this problem is to improve the interfacial interaction between MOF crystals and substrates and the compactness of the MOFs membrane.The research progress of preparation methods and applications in membrane separation field of MOFs membrane were introduced from four aspects:chemical modification and physical modification of substrate,MOFs seed modification as well as 2D material induced growth of MOFs membrane.The mechanism of different modification and preparation methods were particularly explained,and its influence on membrane formation properties and separation performance was analyzed.Besides,the primary challenge in MOFs membrane preparation was summarized,and prospected the development direction of MOFs membrane preparation.
