Article Preview

TiO2 and HA thin film double coating has been proposed. The TiO2/HA thin film was coated on the glass by a Radio Frequency magnetron sputtering, and the characteristic of the thin film has been studied. The absorption of Formaldehyde (HCHO) gas in the TiO2/HA thin film was detected by gas chromatography, and the sterilization of Escherichia coli (E. coli) was evaluated in the antibacterial test. In the deodorization test, HCHO gas remained 0[%], 11[%] and 85[%] for TiO2/HA thin film, TIO2 thin film and thin film respectively. The sterilization result shows that E. coli for TiO2/HA thin film and HA thin film decreased 89[%] and 75[%] respectively.
