Abstract：

In order to improve the interfacial compatibility between the inorganic dispersed phase and the organic continuous phase of the mixed matrix membrane, novel IL@UiO-66-NH2 nanoparticles were designed as fillers to prepare MMMs by coating method. The effect of IL@UiO-66-NH2 content and feed pressure on the gas separation performance of the membrane was investigated. The IL@UiO-66-NH2 particle and mixed matrix membrane were characterized by SEM, XRD and FTIR. The results show that the IL@UiO-66-NH2 nanoparticles were uniformly dispersed in the polyimide matrix and no non-selective voids were formed in the MMMs. The resulting membrane was used to construct the CO2/CH4 separation system. The results show that when the loading of IL@UiO-66-NH2 in the membrane is 15 wt.%, the permeability of CO2 is 26.32 Barrer, and the separation factor of CO2/CH4 is 53.91, which is increased by 46.55% and 26.23% than that of the pure polyimide membrane.
