Abstract :
Polymer electrolytes based on the polyethylene oxide and ammonium perchlorate (PEO: NH4ClO4) dispersed with bismuth sulfide are successfully prepared by in situ method. The electrical characterization of different samples is done by complex impedance spectroscopy, conductivity dispersion curve and Wagner polarization technique. Complex impedance plots are the semicircles and the intercept on the real axis showed the value of the bulk conductivities (10-6 - 10-5 S/cm-1) of the different polymeric samples. The overall conductivity of polymer electrolyte is enhanced with the dispersal of bismuth sulfide, peaks at 6 wt. % then decreases which could be explained by Bunde et al model. Detailed I-V studies show n-type behavior of dispersoid in the composite.
