Description
Summary:Ion conducting biopolymer electrolyte crust based on starch and potassium iodide has been primed through Gelation method. In this exertion we report the details of conductivity, dielectric, dielectric loss tangent and modulus study of starch incorporated with potassium iodide. The values of the parameters that are required in the equation are obtained from Nyquist plots and impedance data. The decrease in bulk resistance value obtained from the Nyquist plots indicates the enhancement of conductivity in crust. The frequency dependence dielectric study shows that the value of dielectric constant is high at lower frequencies and decreases with increase in frequency. The tangent loss peaks shift towards the high frequency side on increased KI concentration which reveals that there is an increase in amorphous content in starch incorporated KI crust. The real and imaginary parts of the electrical modulus show the long tail in low frequency side which depict the membrane is an ionic conductor; also the increase in conductivity is due to the mobile ions.
