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.
