PVA (poly vinyl alcohol)-Fe2TiO5 (PF) and PVA-PVP (poly vinyl pyrrolidone)-Fe2TiO5 (PPF) nanocomposite membranes have been prepared with solutions casting method. Glutaraldehyde (GA) was used as cross linking agent. The nanocomposite membranes were characterized by using AC impedance spectroscopy (IS), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) coupled with energy dispersive x-ray (EDX), tensile strength (TS) and thermogravimetric analysis (TGA). The results showed that the good water uptake and proton conductivity of the PF and PPF nanocomposite membranes respect to the PVA based membrane. PPF nanocomposite membranes containing 3 wt % of Fe2TiO5
nanoparticles and mass ratio of (PVA: PVP 76:23) demonstrated higher water uptake (310℅) and proton conductivity (0.26 S/cm) than that of PF and other PPF nanocomposite membranes
