Herein, we report the modification of poly (ethylene glycol)-polyurethanepolymethylmethacrylate (PEG-PU-PMMA) solid polymer electrolyte using different low molecular weight plasticizers (PEG400, PEG600 and dibutyl sebacate (DBS)) at various concentrations (5, 10, 15 and 20 wt%) through solution-casting method. The formation of plasticized polymer electrolyte, its structural properties and thermal stability are confirmed by FT-IR, SEM, XRD and TGA. The effect of various plasticizers and their concentrations on the ionic conductivity (σ), activation energy (Ea), enthalpy (ΔH), entropy (ΔS) and diffusion coefficient (D) of polymer electrolyte are studied in detail. The highest ionic conductivity of 0.180 x 10-3S cm-1 at 313 K is observed for PEG-PU-PMMA solid polymer electrolyte with20wt% PEG400 plasticizer which is attributed to its high dielectric constant and low molecular weight.
