Abstract:
In this study, Polyacrylonitrile (PAN) was used to prepare the substrate membrane with sponge-like cross section for gas separation composite membrane. The influences of polymer concentration, temperature of coagulation bath, evaporation time and introduction of additives on membrane performance were investigated by Scanning Electron Microscopy and Gel Permeation Chromatography. It indicated that increasing polymer concentration, evaporation time, amount of additives (H2O, ZnCl2 and 1-Butanol) and decreasing temperature of coagulation bath, were all effective methods to regulate the membrane performance and obtain the membrane with sponge-like structure.
