    Abstract

    The plasticized polymer electrolytes composed of poly(epichlorohydrin- ethyleneoxide) (P(ECH-EO)) as host polymer, lithium perchlorate (LiClO 4) as salt, γ-butyrolactone (γ-BL), and propylene carbonate (PC) as plasticizer have been prepared by simple solution casting technique. The effect of mixture of plasticizers γ-BL and PC on conductivity of the polymer electrolyte P(ECH-EO):LiClO 4 has been studied. The band at 457 cm -1 in the Raman spectra of plasticized polymer electrolyte is attributed to both the ring twisting mode of PC and the perchlorate ν 2(ClO 4 -) bending. The maximum conductivity value is observed to be 4.5× 10 -4 S cm -1 at 303 K for 60P(ECH-EO):15PC:10γ- BL:15LiClO 4 electrolyte system. In the present investigation, an attempt has been made to correlate the Raman and conductivity data.
