Effect of ZrO_2 on conductivity of PVC-PMMA- LiBF_4-DBP polymer electrolytes

摘要

The preparation and characterization of compositepolymer electrolytes of PVC-PMMA-LiBF_4-DBP for differentconcentrations of ZrO_2 have been investigated. FTIR studiesindicate complex formation between the polymers, salt andplasticizer. The electrical conductivity values measured by a.c.impedance spectroscopy is found to depend upon the ZrO_2concentration. The temperature dependence of the conductivity ofthe polymer films seems to obey the VTF relation. Theconductivity values are presented and results discussed.
