Synthesis and characterization of PEO:Sr/CuO polymer nanocomposite films and study of their optical, electrical and viscosity properties

Abstract

PEO and PEO:Sr/CuO films have been prepared by the well known solution casting method. The structural studies of the polymer films are studied by XRay diffraction (XRD), Scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) techniques. The optical property is studied by recording UV-visible spectroscopy. The structural properties of polymer films characterized by X-ray diffraction measurements confirm the semi-crystalline nature of PEO which contains crystalline and amorphous regions. The SEM of PEO:Sr/CuO films exhibit characteristic patterns on the film surface. Photovoltaic activity of the films and viscosity measurements of PEO and PEO:Sr/CuO nanocomposite solutions are also studied.
