Abstract

In this study the development and characterization of on modified montmorillonite incorporated on the chitosan based biopolymer matrix by the solvent casting
technique in the form of dimensionally stable and free standing films.The surface modification of MMT has been confirmed by the FTIR analysis. Significantly the effects of modified MMT incorporated bio polymer were investigated by X-Ray diffraction method. From the AC impedance spectroscopic analysis , the proton conductivity has been found to be increases with increasing modified nano clay concentration up to 25% beyond which the conductivity decreases and the highest ambient temperature conductivity has been found to be 5.074X10-3 S/cm. Dielectric data’s like using complex impedance Z* , Dielectric constant and tangent loss were analyzed for prepared polymer electrolyte membrane for the highest conductivity sample at various temperature. Based on the study of relaxation spectra, it is found that the relaxation time decrease with increase in temperature and dopant concentration.
