The nanofibrous anion exchange membranes based on the quaternary salt of poly(4-vinyl pyridine) (PVPy) or poly(1-vinyl imidazole) (PVIm) were prepared by electrospinning method. The electrospinning solutions were mixture of each quaternary polymer salt with poly(vinylidenefluoride-co-hexafluoropropylene) (PVdF-I-IFP) in DMF. The quaternary salts of the polymers were obtained through the reaction with allyl bromide and butyl bromide. The weight fraction of polymer salts in the PVdF-HEP matrix was controlled to adjust the electrospinnability. The chemical structure and surface morphology of membranes were confirmed by ATR-IR, H-1 NMR, and SEM. The properties of membranes, such as thermal stability, ion exchange capacity (IEC), and ionic conductivity, were investigated by using TGA, Mohr titration, and an impedance analyzer, respectively. Also, the chemical stability in acidic and basic conditions was investigated. The performance of prepared membranes as anion exchange membrane dependent on quantity of quaternary polymer salt, was diversely analyzed.
