Abstract :

 Recently, biodegradable polymer electrolytes have gained interest for their application in solid state devices. A novel blend polymer electrolyte with a combination of biodegradable polymer– Poly vinyl alcohol (PVA) and natural polymer– Agar has been prepared by solution casting technique. XRD analysis reveals the amorphous nature of the polymer samples. The ionic conductivity of the prepared polymer electrolyte is found by ac impedance spectroscopy analysis. The maximum ionic conductivity is 3.6738×10–7 S cm–1 at ambient temperature for the film of composition 70mol% PVA:30mol% Agar. The lowest relaxation time at ambient temperature has been found to be 1.479x10–5 sec for 70% mol PVA and 30% mol Agar.
