Poly(vinylidene fluoride) (PVDF)/polymethylmethacrylate (PMMA) hollow fiber ultrafiltration (UF) membranes were prepared via wet spinning method using polyvinylpyrrolidone (PVP) as pore-foaming agent, mixture of dimethyl formamide (DMF) and dimethyl acetamide (DMAc) as solvent, and pure water as an external coagulation solution. Effects of PVDF, PVP and PMMA concentration on performance of the membrane were discussed. The surface and cross-sectional morphology, hydrophilic property, the tensile strength and elongation of the hollow fiber membrane were measured, respectively. Results indicated that the performance of the membrane is the best with a pure water flux of 124 L/m(2).h and rejection rate of 73% to bovine serum albumin (BSA), when the concentration of PVDF, PMMA, PVP, DMF and DMAc are 18, 0.5, 1.5, 40 and 40 wt%, respectively.
