Abstract:
1. A process for preparing a TiO 2 thin film having photo-induced antibacterial and antivirus activities comprising the steps of: a) providing a reverse micelle solution containing dispersed nano-droplets comprising an organic continuous phase, a non-ionic surfactant, and water; b) adding a titanium alkoxide in a concentration from 0.2 to 0.3 M and a stabilizer consisting essentially of a 2,4-diketone in an amount from 2 to 5% by volume of the reverse micelle solution to the reverse micelle solution and subjecting the titanium alkoxide to hydrolysis in said nano-droplets of the reverse micelle solution to form a TiO c) forming a wet film onto a substrate dipped into the TiO d) drying the wet film and calcining the dried film.
