| Abstract | Zinc oxide nanoparticles on silica matrix thin films were prepared by the sol-gel method and dip coating on ceramic tiles. In this study, EC (ethyl cellulose) and TP (alpha-terpineol) used as a binder and a solvent in sol-gel method, respectively, were studied on the characteristics of thin films. The thin films were dried and calcined at the temperature of 500C and 600C soaking 30 min with the heating rate of 1 C/min. The result of glancing X-ray diffraction showed that thin films were ZnO phase on the amorphous phase of silica matrix. Scanning electron microscope showed the ZnO nanoparticles dispersed on thin films and depended on the concentration of EC and TP. The antibacterial activity test on Gram positive ( Escherichia coli) and Gram negative ( Staphylococcus aureus) bacteria were evaluated that films have good photocatalytic under UV irradation, and also exhibited high antibacterial activity under repeating for 3 times. As mentioned above, ZnO nanoparticles on thin film can be applied on ceramic tiles for antibacterial activity by using photocatalytic process for eco-friendly, low cost and easy for preparation. |
