英文摘要	in this paper, co2-philic membranes are prepared with poly(amide-12-b-ethylene oxide) (pebax1074) and glycerol triacetate (gta) by polymer blending, which show excellent compatibility for different gta compositions. the additive gta into pebax1074 matrix can improve the chain mobility, induce high co2-philicity and decrease membrane crystallinity. with the increase of gta mass content from 0 to 80 wt%, co2 permeability increases from similar to 135 to similar to 1800 barrer, and co2/h-2 ideal selectivity also increases from 10 to 19. for pebax1074/gta blend membranes, the threshold mass content of gta (c) which corresponds to the rapid increase of gas permeability is about 40 wt%. when gta mass content is not more than c* (40 wt%), the gas permeation properties are mainly dominated by pebax1074. but for pebax1074/gta blend membranes with gta mass content above c* (40 wt%), their gas permeabilities and co2/light gas selectivities both change dramatically, which are mainly influenced by gta. these membranes show excellent separation performance for co2/n-2 and co2/h-2, especially for co2/h-2 separation.
