英文摘要 | in this paper. asymmetric membranes are prepared with p84 (btda-tdi/mdi co-polyimide)/n-methyl-2-pyrrolidone (nmp)/-gamma-butyrolactone (gbl) and polyetherimide (pei)/nmp/gbl. casting solutions by wet phase-inversion process and the transition of membrane morphology is investigated with different flat sheet and thickness-gradient membranes. for the thickness-gradient membranes, with the increase of membrane thickness, the membrane morphology changes from sponge-like to finger-like structure at the critical structure-transition thickness l(c). meanwhile, the general sponge-like structure thickness l(gs) underneath the membrane surface is almost a constant. and the morphology of thickness-gradient membranes is illustrated with three different thickness regions. |
