Abstract:
Polymer electrolyte composites based on the polyethylene oxide (PEO) and ammonium perchlorate dispersed with the cupper sulfide is successfully prepared and charz acterized with the electrical studies. The a.c. conductivity measurement of the polymer electrolyte composites is done by the complex impedance studies. Plots between the conductance (G) and susceptance (B) are the semicircles and the intercepts on the real axis gives the value of bulk conductance of various polymeric films. Bulk conductivity and dispersoid wt. % plot showed the conductivity enhancement with variation ~10^-6 to 10^-5 S/cm^-1 with the peak value at 7.6 x 10^-6 S/cm. The decrease in the overall conductivity after the peak value could be explained by Mayer’s space charge model. The frequency dispersion plot showed the plateau region in the frequency range from 10 Hz to 10 KHz. Detailed I-V studies show p-type behavior of dispersoid in the composite.
