Photocatalytic Antibacterial Effect to TiO2 Thin Film on Ceramic Plate
Abstract:
TiO2 and Pt/TiO2 antibacterial thin films were prepared by sol-gel process and dip-coating method on the substrate of ordinary glazed ceramic plate. The relationship between film thickness, exposure time and antibacterial effect of the thin films on Colibacillus and Staphylococcus aureus under the irradiation of ultraviolet and sunlight was studied. TiO2 films of about 80 nm and 55 nm thicknesses and Pt/TiO2 films of about 50 nm thicknesses showed antibacterial efficiencies of 90% or more on Colibacillus after 30 min ultraviolet irradiation. The experimental results has also shown that the ultraviolet irradiation effect is better than Sun does in the same concentration of the film. TiO2 film of about 55 nm thicknesses presented the best efficiency on the Staphylococcus aureus.
