Dielectric, AC Conductance of Chalcone Moiety, Metal Oxide Nanocomposite Doped Thin Polymer Film: Synthesis and Characterization

For conducting use, an organic molecule chalcone (1-(2,4-dichlorophenyl)-3-(4-hydroxy-phenyl)-prop- 2-en-1-one (DCHP) and metal oxide nanocomposite (MONC) doped polymer thin films were prepared. In addition, polyvinyl alcohol (PVA) and chitosan (CS) was utilized as a host polymer. The features of successfully prepared thin polymer films were characterized. The XRD analysis revealed the nano-sized (40-150 nm), crystalline phases and semi-crystalline behaviour of polymer films. The XPS and EDX confirmed the elements of PVA, CS, DCHP, MONC4 and MONC5, as well as the oxidation states of MONC4 and MONC5 sample films. The morphology of the prepared polymer film revealed an even distribution, a smooth surface and a blossoming flower-like structure from the SEM results. The TGA study revealed the multi-stage decomposition upon heating, but no complete decomposition for the produced film containing MONC4 and MONC5 thin films. The bonding between doped materials and the host polymer in the film was confirmed by FT-IR studies. The produced thin polymer composite film containing metal oxide nanocomposites and DCHP exhibited a high dielectric property and high AC conductance of 1.12 × 10-6 S cm-1 at room temperature.
