| Abstract: | Polyvinylidene fluoride (PVDF) ultrafiltration membranes were prepared by phase inversion method. The mean pore size of membranes was determined by small-angle X-ray scattering. This paper,based on the previous work, continued to study the effects of some preparing conditions,the evaporating time of nascent membrane and the formula ratio of precipitation bath,on the mean pore size. On the other hand,some hydrophilizing methods for hydrophobic PVDF ultrafiltration membrane were studied. |
