| 英文摘要 | this work a series of mixed matrix membranes (mmms) containing metal organic frameworks (mofs) were fabricated to investigate the influence of post-treatment on their gas separation properties. it was revealed that gas permeabilities increased considerably as treatment temperature increased from 150 degrees c to 180 degrees c and remained almost unchanged after 200 degrees c; gas permeability of mmms from 200 degrees c treatment was about 3 times higher when compared with mmms treated at 150 degrees c. from results of physical characterization including tga, xrd, sem, atr-ftir and nitrogen absorption it was inferred that higher temperature treatment induced gas permeability increase should be mainly attributed to more effective removal of residual solvent in micro-pores of mofs; and gas permeation properties of mmms with different treatment durations from 24 h to 96 h further confirmed our conclusion. this heat treatment induced permeability increase phenomenon was further verified by varying the polymer and mof combinations. at the end cu-3(btc)(2)/odpa-tmpda mmms with different mof loadings were prepared and the one with best performance appeared at 40 wft loading: a dramatic increase of co2 permeability from 47.7 barrer to 260.7 barrer with almost unchanged co2/ch4 selectivity from 29.26 to 27.75.
