Electrochemical and Dielectric Studies of Poly(Ethylene Oxide)/Mg(ClO3)2 Composites
Poly(ethylene oxide)–Mg(ClO3)2 composites have been prepared by slurry method using acetonitrile as an solvent with different weight percentage. The prepared composites were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. FTIR study shows the characteristic vibrational bands of the PEO and dopant metal chlorate, confirms the formation polymer composites. SEM image revels that the composites are highly agglomerated and irregular in shape. The dielectric studies were carried out in a frequency range from 102–106 Hz. From dielectric studies it is observed that the permittivity and dielectric loss value decreases with increase in frequency. Electrochemical cells parameters shows that 25 wt% of PEOMg(ClO3)2 composite has high charge density, open circuit voltage and polarization current with respective to the charging time.
