摘要: Polysulfone (PSf) membrane is catogorized as hydrophobic that easily fouled during operation process. The presence of second hydrophilic polymer which added into casting solutions plays a crucial role in adjusting the properties. This was employed membranes order to improve hydrophilicity and performance well formed antifouling ultrafiltration (UF) membranes. In this study, polymer, cellulose acetate phthalate (CAP) polysulfone by blending technique produce PSf/CAP blend Flat sheet asymmetric were prepared wet phase inversion method. results revealed an increase CAP increased properties compared pure PSf membrane. significant changes size numbers microvoids macrovoids morphological structures due promote instantaneous liquid-liquid demixing
