Synthesis, Characterization, and Studies of PVA/Co-Doped ZnO Nanocomposite Films

Abstract

ABSTRACT Polymer nanocomposites are made up of two or more phases wherein the inorganic particles are dispersed in a polymer matrix. The present article deals with Co-doped ZnO embedded in a polyvinyl alcohol (PVA) matrix using a sol-gel method. The synthesized nanocomposites were structurally characterized using X-ray diffraction (XRD) and the optical properties were studied using photoluminescence and ultraviolet-visible (UV-Vis) spectroscopy. Thermal studies including thermogravimetric analysis (TGA) were conducted to the study stability of the nanocomposites.
