Dependency of the AC conductivity of blend nanocomposites on the Lil and ZnO percent

The polymer electrolytes were formulated using the solvent casting technology of the present work. Under some conditions, the electrolyte content of polymers was analyzed in constant percent PVP/PAN (25:75), EC and PC (1: 1) with varying proportions of Lil (10, 20, 30, 40, 50) percent and iodine l2 = 10 % of salt wt. As the Lil salt weight ratio rises, the conductivity increases and achieves a maximum value of 0.032558 (S.cm−1) at room temperature. The conductivity was also raised with the increase in the temperature within the range (293 to 343 K), and also increased with the nano-ZnO was added, a slight rise of approximately 0.0218 S.cm−1 at (0.2g) of ZnO. The results showed that the FTlR results for electrolytes with only Lil salt indicated a significant degree of reaction between the polymer blends (PVP & PAN) and Lil salt molecules. That focuses on the complexity between mixtures of polymers and Lil salt. From observations of the nanocomposites electrolyte, the wide peak becomes narrower after adding the ZnO nanomaterial to the Lil salt. The dielectric reaction decreases with the growth of frequency at room temperature. The high dielectric permittivity of the polymer at lower frequencies can be attributed to the dipoles providing sufficient time for alignment with the electric field, which results in a higher polarization.
