Polyvinyl Alcohol, Chitosan Polymer Film Containing Chalcone, Metal Oxide Nanocomposite: Synthesis Characterization and Electrical Properties

PVA, Chitosan film containing metal oxide nanocomposites (MONC) or chalcone moiety, prepared with a thickness of around 0.03 cm. Different molecular weights of MONC are used for the preparation of different polymer composite films. FT-IR, XRD, XPS, EDX, and TGA techniques were used to characterise the prepared film. Semicrystalline (40-150 nm) behaviour is observed for prepared film, which is confirmed by XRD, and the film undergoes multistage decomposition on heating, confirmed by TGA. SEM analysis concludes the film has a blooming flower like structure on the surface. Different elements of the polymer and dopant were confirmed using XPS and EDX analysis. FT-IR analysis suggests that there is no chemical interaction between the polymer and the hosting materials. The film shows a AC conductivity value of 1.36 x 10(-5 )Scm(-1), and it shows higher dielectric properties.
