Abstract :

Various polymers such as PVA, PVAc, PVP and etc., doped with ammonium salts have been studied for proton conduction. But the study of proton conduction in polymer PAN is scarce. The proton conducting polymer electrolytes composed of polyacrylonitrile (PAN) with ammonium nitrate (NH4NO3) in different molar ratios, have been prepared by solution casting method, using DMF as solvent. The increase in amorphous nature of the polymer electrolytes has been confirmed by X–ray diffraction analysis (XRD). The complex formation between polymer and dissociated salt has been confirmed by Fourier transform infrared spectroscopy (FTIR). The ionic conductivity, dielectric permittivity (ε*) and electric modulus (m*) have been calculated from the ac impedance spectroscopy in the frequency range 42HZ–5MHZ. The activation energy of doped PAN polymer electrolyte is calculated using Arrhenius plot. Based on the study of relaxation spectra, it is found that the relaxation time decreases with increase in temperature
