Polyphenylsulfone (PPSU) was employed to fabricate novel alkali resisting ultrafiltration membranes via phase inversion process and the membrane structure was tailored by adjusting the kinetics of phase separation. The effects of polyvinylpyrrolidone (PVP) molecular weight (Mw) and concentration on the casting solution and the performance of PPSU membrane such as tensile strength, morphology, hydrophilicity,...
