摘要：
Porous asymmetric PVDF membranes were prepared by the phase inversion process induced by a nonsolvent. The effect of pore-forming hydrophilic additives on the membrane morphology and transport properties was investigated. It was found that membranes prepared with hydrophilic polymer additives can offer higher pure water flux, higher porosity and lower pepsin rejection. PEG 10 000 can be used as a good pore forming additive to prepare PVDF membrane with higher pure water flux and relatively high pepsin rejection.
