| 英文摘要 | three metal-organic frameworks(mofs) with different structure, particle size and gas adsorption properties were synthesized: micron-scale cu-3(btc)(2), sub-micron zif-8 and s-cu-3(btc)(2). nitrogen adsorption-desorption isotherms of mofs showed that zif-8 and cu-3(btc)(3) possessed quite large bet surfaces (1653 and 1439 m(2)/g), and bet surface of s-cu-3(btc)(2) was 171. 4 m(2)/g. mofs were directly introduced into polyimide to fabricate mixed matrix membranes(mmms). it was proved by xrd and ftir-atr characterizations that mofs had no structural or chemical degradation in mmms. gas permeation test result indicated that gas separation properties of mmms were enhanced as mofs were added. comparing with pure polyimide membrane, the adding of zif-8 or cu-3(btc)(2) brought gas permeability increase about 3 times, gas permeability of mmms with s-cu-3(btc)(2) increased 175%. meanwhile gas selectivies for o-2/n-2 and co2/ch4 decreased slightly. |
