Non-UV driven self-cleaning and anti-fogging glasses prepared by ultrasonic nebulization of TiO_2 hydrosol

摘要

Highly transparent glasses coated with TiO_2 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°C. In this paper, the effect of film thickness and the role of PEG in facilitating the pore formation and interacting with TiO_2 are also discussed.
