Characterization of nanocomposite polymer electrolyte based on P(ECH-EO)

ZrO2 nanoparticles have been prepared by poly acrylamide gel route. The synthesized nanosized ZrO2 have been incorporated into plasticized polymer electrolyte (PPE), P(ECH-EO): LiClO4: γ-BL system to understand the effect of ZrO2 on the ionic conductivity. The X-ray diffraction pattern of the synthesized ZrO2 nanoparticles reveals the crystalline phase. The X-ray diffraction patterns of P(ECH-EO) based NCPEM confirm the polymer-salt-nanoparticle complexation. The scanning electron microscope image of NCPEM confirms that the ZrO2 nanoparticles were distributed uniformly in the polymer matrix. The presence of nano filler has increased the ionic conductivity and the maximum dc conductivity value is found to be 6.24×10−6 S cm−1 at 303 K for 96(PPE): 4ZrO2 (mol%).
