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

    By M. Seshu Kumar, M. C. Rao

    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 …

    Effect of Nanofiller on FTIR, DSC and DC Conductivity Studies of PVP Based Polymer Films

    By M. Seshu Kumar, M.C. Rao

    Abstract: Nanocomposite polymer films (NCPs) are prepared by doping of potassium acetate (CH3COOK) in polymer of polyvinyl pyrrolidone (PVP) by dispersing aluminium oxide (Al2O3) by different weight percentile ratios using solution cast technique. The obtained NCPs’ films were characterized and reported. Complex analysis between NCs and host polymer was confirmed by FTIR. DSC analysis states the glass transition temperature, Tg=77oC at which the phase transformation changes from glassy to rubbery amorphous …

    Preparation and Structural Characterization of PVP-CH3COONa Based Polymer Films

    By M. Seshu Kumar, M. C. Rao

    Abstract: PVP based polymer electrolyte films were prepared by dissolving sodium acetate with different wt.% compositional ratios by solution cast technique. XRD revealed the crystalline phase of the prepared samples. XRD pattern demonstrated a wide peak at 29.35° attributed to the host polymer indicating orthorhombic cross section showing semicrystalline phase. FTIR and Raman studies affirmed to identify the functional group of the materials, bond formation between the dopant salt and the …
