Poly (vinylidene fluoride) (PVDF) hollow fiber membranes were successfully prepared using DMAc/γ-BL as the mixed diluent and PEG as the additive through modified thermally induced phase separation (M-TIPS) process. The membranes prepared were characterized by scanning electron microscope. Their properties such as water permeability and mechanical properties were also determined. The results show that PVDF membranes have spherical crystallites structure with interconnected network structure because of the combination of solidliquid and liquid-liquid phase separation. When using 25wt% aqueous ethanol solution as the coagulation, the PVDF hollow fiber membrane shows the tensile strength, i.e.4.59MPa and pure water flux, i.e.415 L/ (m2·h).
