In this work, films of polyvinyl pyrrolidone (PVP) polymer electrolyte complexes with different concentrations of VO2+ ions (1 to 5 mol%) were prepared by solution casting technique. The thermal, structural and morphological properties of pure and VO2+ doped PVP polymer films were investigated using TGA, XRD and SEM. Based on dTG and TGA data shows three different stages of weight loss and the thermal stability of all the investigated samples were improved. The increased amorphous nature of PVP polymer film due to doping has been identified from XRD pattern.. The SEM elucidates the surface morphology of the pure and VO2+ ions doped PVP films indicates a continuous microstructure is relatively rough of the polymer film, which suggests the amorphous nature. ..
