Poly (vinylidene fluoride) (PVDF) membranes were prepared by the phase inversion method using N,N-dimethylacetamide (DMAc) as polymer solvent and water as non-solvent. Different crystal form of Poly (vinylidene fluoride) (PVDF) were studied after PVDF membranes preparation as function of coagulation bath temperature and PEG inclusion in polymer dope solution. The low temperature coagulation bath (25 ˚C) mainly resulted to β phase formation, whereas higher temperature coagulation bath (60 ˚C) resulted to formation of more structures of α phase. Besides, the β phase content in PVDF decreased via 5 wt% PEG inclusion into PVDF.
