ABSTRACT
Ionic liquids (ILs) are salts with low melting point close to room temperature. They have interesting solvent properties and are able to dissolve some polar molecules. Polyvinyl formal-IL (1-Ethyl-3-methylimidazoliumtosylate) nanocomposite electrolyte with layered filler was synthesized by solution cast technique. Changes in surface morphology have been observed using optical microscopy and scanning electron microscopic (SEM) images. Variation of dielectric constant, dielectric loss, tangent loss and modulus spectra with frequency and temperature were studied with the aid of impedance spectroscopy.
