Influence of Al2O3 Nanofiller on Morphological and Discharge Studies of PVP: CH3COOK Films

Abstract

Nanocomposite polymer (NCP) films were prepared by doping potassium acetate with polyvinyl pyrrolidone (PVP) by complete dispersion of aluminum oxide (Al₂O₃) with different wt% proportions by using solution-casting method. The acquired NCPs films were characterized systematically. The crystalline structure of the prepared NCPs films was confirmed by XRD. The little agglomeration and grain sizes involved in the films were analyzed by SEM. The energy bandgap values were observed to be at 3.16 eV for the wt% ratio of PVP: CH₃COOK: Al₂O₃ (80:20:1%). The most extreme ionic conductivity was found to be 1.08´10^-3 S/cm for the prepared PVP+CH₃COOK: Al₂O₃ (80:20:1%) film. From the charge discharge characteristics, it was concluded that the film with wt% ratio of PVP+CH₃COOK: Al₂O₃ (80:20:1%) possesses long durability when compared to other wt% ratios.
