摘要
Abstract
Mixed matrix membranes based on metal organic frameworks(MOFs)have the performance advantages of both polymers and MOFs materials,and are research hotspot in the field of H2/CO2 gas separation.In this paper,CAU-1 with different particle sizes was dispersed into polyimide(PI)substrate by in-situ polymerization,and MOFs fillers and mixed matrix films were characterized by XRD,SEM,TG,FTIR,etc.,to explore the effects of particle size and heat treatment temperature on H2/CO2 separation performance.The results showed that,compared with the pure polymer membrane,the separation effect of mixed matrix membrane was significantly improved.In-situ polymerization could significantly improve the interfacial compatibility of MOF and polymer,and the separation factor of H2/CO2 of PI/CAU-1 membrane after optimization of CAU-1 particle size and heat treatment temperature could reach 8.4.关键词
