Methods for forming doped titanium dioxide coatings are disclosed. Sol-gel compositions are prepared having at least one dopant, are formed on a substrate, and heated at a temperature sufficient to form a doped anatase titanium dioxide coating. Doped titanium dioxide coatings having at least one of improved antimicrobial properties, self-cleaning properties, hydrophilicity, and/or activation time are also disclosed. Substrates comprising such coatings are also disclosed.
Linvention concerne des procédés de formation de revêtements à base de dioxyde de titane dopé. Des compositions sol-gel contenant au moins un dopant sont préparées, déposées sur un substrat et chauffées à une température suffisante pour former un revêtement à base de dioxyde de titane anatase dopé. Linvention concerne également des revêtements à base de dioxyde de titane dopé dont les propriétés antimicrobiennes, les propriétés autonettoyantes, le caractère hydrophile et/ou le temps dactivation sont améliorés. Des substrats comprenant de tels revêtements sont également décrits.
