Improved Performance of PAN-based UF Membrane with PAN-g-PVA Amphiphilic Copolymer

The present study focuses on the effect of poly (acrylonitrile) (pan)-g-poly (vinyl alcohol) (pva) amphiphilic copolymer as an additive on fabrication of pan-based uf hollow fiber membrane. the pan-based hollow fiber membranes with different copolymer composition in dope solution were prepared via dry-wet phase inversion process. compared to pan-based membrane, membranes incorporated with pan-g-pva copolymer displayed good morphology and better hydrophilicity. it is found that pure water flux of the membrane incorporated with amphiphilic copolymer was 5 times higher than that of control membrane, recording 244.97 l/m2.hr when tested at 1 bar. results also showed that the uf membranes incorporated with amphiphilic copolymer were able to retain efficiently bovine serum albumin (bsa) (66 kda) and possessed better anti-fouling performance.
