Abstract
Solventfree films of poly ethylene oxide–silver triflate PEO–AgCF3SO3/MgObased nanocomposite polymer electrolytes PEO50AgCF3SO3–x wt MgO x = 1 3 5 7 and 10 obtained using solution casting technique were found to exhibit an appreciably good complexation of MgO nanofiller within the polymer electrolyte system and nonDebye type of relaxation as revealed by Fourier transform infrared and complex impedance analyses Optimized filler 5 wt MgO when incorporated into the polymer electrolyte resulted in a maximum electrical conductivity of 2 × 10−6 S cm−1 in conjunction with a silver ionic transference number t Ag+ of 023 at room temperature 298 K Detailed structural thermal and surface morphological investigation indicated a slight reduction in the degree of crystallinity owing to the addition of MgO nanofiller
