Effect Of Ceramic Oxide On The Ionic Conductivity Of Polymer Electrolytes

S.Rajendran, Ravi Shanker Babu, T.Sathiya Prabha


Composite polymer electrolytes consisting of polymers poly (acrylonitrile)(PAN), poly (methyl methacrylate) (PMMA) with ethylene carbonate (EC) and propylene carbonate(PC) as plasticizers, lithium tetra fluoro borate (LiBF4) as a salt and TiO2 as an inert ceramic additive are prepared by solvent casting technique. The complex formation has been confirmed from XRD and FTIR studies and the thermal stability of the film is ascertained from TG/DTA studies. The maximum conductivity value is found to be 7.475ï‚´10-4S/cm for PAN(15)-PMMA(5)-LiBF4-(8)- EC(42)-PC(30)+15wt% TiO2 film. The effect of TiO2 concentration on ionic conductivity was studied using ac impedance spectroscopy and the results are discussed.
