    摘要: In this study, dual-layer spinneret was used to fabricate poly (vinylidene fluoride) (PVDF) hollow fiber membrane by using PVDF/NMP dope solution and ethanol solution as the inner-layer solution and outer-layer solution, respectively. The effects of air gap distance (corresponding to the stand time of nascent hollow fiber membrane in the ethanol bath) and PVDF polymer dissolved temperature on the morphology and mechanical property were investigated. The result shows that the PVDF hollow fiber membrane with porous surface can be prepared. Moreover, the tensile strength at break as well as elongation at break of the PVDF hollow fiber membrane decreased as increasing the dissolved temperature of PVDF polymer.
