ABSTRACT
In the present work, the ion transport property of Polyvinyl Formal (PVF)-based nanocomposite polymer electrolytes has been investigated upon dispersal of Multiferroic (BFO) nanosized filler particles. With the aim to developed the lithium ion (Li+) conducting nanocomposite polymer electrolytes (NCPEs) Lithium Acetate has been chosen as doping salt. NCPE films were prepared by solution cast technique while Multiferroic nano powder was synthesized through sol-gel process. The formation of nanocomposite has been ascertained by XRD pattern. Variations of dielectric constant, dielectric loss, tangent loss and modulus spectra with frequency and temperature were studied with the aid of impedance spectroscopy data. XRD result shows that the doping of salt increases amorphousness through polymer salt complexation. The changes in surface morphology have been investigated in optical and SEM images observation. CV measurement of NCPEs suggests a broad electrochemical window utility in practical electrochemical devices.
