Thermal, dielectric and antimicrobial properties of polystyrene-assisted/ITO:Cu nanocomposites
Polystyrene membranes were found to be an effective-assisted material in the growth of undoped and doped indium–tin–oxide (ITO) with different concentrations from 3 to 7 wt% of CuO nanoparticles. Nanocomposites were characterized by XRD, FT-IR, HR-SEM/TEM, and dielectric measurements. Polystyrene-as...

Summary: | Polystyrene membranes were found to be an effective-assisted material in the growth of undoped and doped indium–tin–oxide (ITO) with different concentrations from 3 to 7 wt% of CuO nanoparticles. Nanocomposites were characterized by XRD, FT-IR, HR-SEM/TEM, and dielectric measurements. Polystyrene-assisted ITO nanocomposites (ITO/PS) showed the high crystalline phase with lattice fringes, and well agreed on the cubic phase of ITO. As the concentration of CuO increases in ITO/PS nanocomposite, the conductivity decreases. Differential scanning calorimetry/thermogravimetric analysis showed a good thermal stability of the prepared nanocomposites. The increase of CuO wt% did not affect the major degeneration temperature and the thermal stability of undoped composite. The highest conductivity was obtained for ITO doped with 7 wt% of CuO. The formed Polystyrene-assisted ITO:Cu nanocomposites demonstrated a considerable antimicrobial activity against non-filamentous fungi (
Candida albicans
), Gram-positive bacteria (
Bacillus mycoides
), and Gram-negative bacteria (
Escherichia coli
) at all tested concentrations (3.0–7.0 wt% of CuO) with maximum activity at 7.0 wt% of CuO. |
