ABSTRACT Film of PEO containg AgCF3SO3 were prepared by the solution casting technique. Fourier transform infrared (FTIR) spectroscopy have been carried out on a series of complexes containing poly (ethylene oxide) PEO and silver triflate (AgCF3SO3) salt. Spectral analysis of all the samples has revealed the complexation of silver ions with oxygen in PEO. The ac conductivity and electrical modulus of the samples prepared have been analyzed. The ac conductivity was observed to obey the Universal power law. The temperature dependence of the power law exponent n is reasonably interpreted by the overlapping large polaron tunneling (OLPT) model. The imaginary part, M” of electrical modulus shows the formation of dispersion peak. The plot of log conductivity relaxation times and log sigma as a function of salt concentration was in accordance with each other.
