Non-UV Driven Self-Cleaning and Anti-Fogging Glasses Prepared by Ultrasonic Nebulization of TiO2 Hydrosol

Article Preview

Abstract:

Highly transparent glasses coated with TiO2 hydrosol and polyethylene glycol (PEG) have been successfully fabricated via ultrasonic nebulization technique. Experimental evidences have indicated that the obtained glass surfaces show excellent non-UV activated superhydrophilic wetting and antifogging performance. These properties are significantly affected by calcination temperature and the optimal value is 600 oC. In this paper, the effect of film thickness and the role of PEG in facilitating the pore formation and interacting with TiO2 are also discussed.
