The Fabrication of Titanium Dioxide (TiO₂) Thin Film via Deposited Spray Pyrolysis Using for Antibacterial Applications

Abstract:

Titanium dioxide (TiO₂) is coated onto the materials (e.g. glass ceramic) to inhibit the bacteria growth. TiO₂ has become a popular photocatalyst for both air and water purification. It has also shown to be very active for bacterial destruction even under UV light. The photocatalytic of TiO₂ involves the light-induced catalysis of reducing and oxidizing reactions on the surface of materials. The spray pyrolysis technique for material synthesis in thin-film configuration is an interesting option due to the use of inexpensive precursor materials and low-cost equipment suitable for large-area coatings. In this research, TiO₂ thin films were deposited onto glass substrates using spray pyrolysis technique. Escherichia coli (E.coli) was used as testing bacteria. TiO₂ thin films showed some antibacterial effect in the halo test.
