Abstract
Ethylene-vinyl alcohol (EVAL) membranes with particles-bonded structur e are prepared by phase inversion from DMSO solvent into the coagulati on baths of water and isopropanol (IPA) mixture. It is based on contro lling the relative diffusion rate of solvent to nonsolvent and the liq uid-liquid demixing area. Using this analysis, it can explain the effe cts of adding IPA to the water bath on the formation of particles and the suppression of macrovoids. The results proposed here are believed to be valid also for other systems. Copyright (C) 1996 Elsevier Scienc e Ltd.
