Polyvinylidene fluoride (PVDF) membranes were prepared via the phase inversion method. The focus of this paper was put on the effects of four specific solvents with different solubility power including hexamethylphosphoramide (HMPA), trimethylphosphate (TMP), N,N-dimethylformamide (DMF) and triethylphosphate (TEP) on membrane polymorphism. Polymorphism of PVDF membranes was analyzed by wide-angle...
Polyvinylidene fluoride (PVDF) flat sheet membranes with inter-connected pores were prepared via a non-solvent assisted thermally induced phase separation (Nat-ips) process. Triethylphosphate (TEP) was used as the latent solvent to prepare the metastable PVDF casting solution. The asymmetric ultra- and symmetric micro‐filtration membranes were respectively prepared by adjusting the polymer concentration...
