Application of Metal Organic Frameworks Materials in Gas Separation Membrane

Metal organic frameworks (MOF) are a new type of material with the advantages of high specific surface area and adjustable pore size. The preparation of MOF membranes on this basis overcomes the shortcomings of poor interfacial compatibility and thermal stability of MOF materials. It has good application prospects in the field of gas separation. This article introduces the functional layer application, physical blending, interfacial polymerization, and graft modification of MOF membranes. The performance improvement of each method for different gases is briefly described. The mechanism analysis of the improvement of separation performance is carried out, and each method is compared. The advantages and disadvantages of the method. Finally, it is pointed out that the interfacial polymerization of MOF film is the future development direction, and suggestions for future research are put forward.
