Polyethersulfone (PES) hollow fiber ultrafiltration (UF) membranes were fabricated using methanol, ethanol, n-propanol as well as water as additives and N-methyl-2-pyrrolidone (NMP) as a solvent. Asymmetric hollow fiber UF membranes were spun by wet and dry/wet phase inversion method from 18 wt.% so

## Abstract Polyethersulfone (PES) hollowβfiber membranes were fabricated using poly(ethyleneglycol) (PEG) with different molecular weights (MW = PEG200, PEG600, PEG2000, PEG6000, and PEG10000) and poly(vinyl pyrrolidone) PVP40000 as additives and __N__βmethylβ2βpyrrolidone (NMP) as a solvent. Asym
Conditions for finger-like void formation in polysulfone (PS) ultrafiltration membranes were studied empirically. It was found that both the "mixability parameter" which was obtained in separate titration experiments and the viscosity of coagulants could be used to predict membrane morphology. It wa
