Effect of ZrO2 on conductivity of PVC�?�PMMA�?�LiBF4�?�DBP polymer electrolytes

[摘要] The preparation and characterization of composite polymer electrolytes of PVCâ€�?�PMMAâ€�?�LiBF₄â€�?�DBP for different concentrations of ZrO₂ have been investigated. FTIR studies indicate complex formation between the polymers, salt and plasticizer. The electrical conductivity values measured by a.c. impedance spectroscopy is found to depend upon the ZrO₂ concentration. The temperature dependence of the conductivity of the polymer films seems to obey the VTF relation. The conductivity values are presented and results discussed.
