【 摘 要 】

The preparation and characterization of composite polymer electrolytes comprising PEO and LiClO₄ with different concentrations of ZnO nanoparticles are studied. Conductivity measurements were carried out and discussed. In order to ascertain the thermal stability of the polymer electrolyte with maximum conductivity, films were subjected to TG/DTA analysis in the range of 298â€�??823 K. In the present work, FTIR spectroscopy is used to study polymer structure and interactions between PEO and LiClO₄, which can make changes in the vibrational modes of the atoms or molecules in the material. FTIR spectra show the complexation of LiClO₄ with PEO. The SEM photographs indicated that electrolytes are miscible and homogeneous.
