Characterization of plasticized PMMA�?�LiBF4 based solid polymer electrolytes

[摘要] Polymer electrolyte films prepared from poly(methyl methacrylate) and LiBF₄ with different concentrations of plasticizer (DBP) are described. The formation of polymerâ€�?�salt complex has been confirmed by FTIR spectral studies. The temperature dependence of conductivity of polymer films seems to obey the VTF relation. Values of conductivities of the polymer complexes are presented and discussed.
