Abstract
Nanocomposite solid polymer electrolytes comprise of PMMA (poly methyl methacrylate), PVP (poly vinyl pyrolidone), MSA (methanesulfonic acid) and TiO2 as nanofiller were prepared by solution casting technique at different compositions. Sample with 1 mol% incorporated TiO2 has shown maximum conductivity and its value was found as 2.82 ×10-5 S/cm. The value of conductivity has been enhanced to about 31% upon the addition of nanofiller. The relaxation time for all the prepared composites as well as for the composite having maximum conductivity at various isotherms have been calculated from the loss tangent plot. The frequency and temperature dependence of dielectric constant and dielectric loss nanocomposite solid polymer electrolytes have also been studied. The modulus analysis confirms the non-Debye type formalism in the prepared composites.
