خلاصه مقاله:
In this study, polysulfone (PS) membranes were prepared via immersion precipitation from quaternary systems containing N, N-imethylacetamide (DMAc) as solvent, polyvinylpyrrolidone (PVP) and acetone as additive. The presence of acetone in the casting solution declined the flux due to formation of membranes with denser skin layers. Evaporation of acetone is responsible for tighter membrane structures.
