Investigation of Antibacterial Properties of Soda Calcium Borosilicate Glass Doped with TiO2
Abstract:
The borosilicate glasses doped with TiO2 were prepared by the melt-quenching technique in compositions SiO2B2O3CaO-Na2O, and investigate their physical, optical and antibacterial properties. The result found that, after dope TiO2, the density was decreased. The densities of glasses are not depending on TiO2 concentration. The cutoff wavelength was shifted to longer wavelength with increasing of TiO2 concentration from 360 nm (undoped TiO2) to 395 nm at 7.5 % of TiO2 concentration. The E. coli. was decreased due to TiO2 generates reactive oxygen species from photocatalysis phenomena.
