Development of Particles Dispersion Type Sprayed Coatings with Water-Repellency and Photo-Catalytic Activity
The sprayed coating containing fl uorine-carbon showed high water repellency (the contact angle for water droplet was 145°). However, the water repellency of the sprayed coating decreased with adsorption of organic materials, NOx, and SOx, which discharged from the automobile. To remove the adsorption compounds from the coating surface, we decide to add titanium oxide (TiO2) in the coating, which could be able to oxidize the surface adsorption compounds photo-catalytically. It was found that the particles dispersion type sprayed coatings prepared by fl ame spray technique using aluminum tubing fi lling with fl uorine-carbon (15.2mass%) and titanium oxide (0.5mass%) had high photo-catalytic activity for liquid phase decomposition of methylene blue without decreasing waterrepellency.
