Abstract
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.
Claims23
A method of forming a doped anatase titanium dioxide coating on a substrate, comprising:
- preparing a titanium dioxide sol-gel composition comprising at least one dopant;
- coating the substrate with the sol-gel composition;
- and
- heating the coated substrate to form a doped anatase titanium dioxide coating.
A method of improving at least one of antimicrobial properties, self-cleaning properties, hydrophilicity, and activation time of a titanium dioxide coating, comprising:
- preparing a titanium dioxide sol-gel composition comprising at least one dopant;
- coating a substrate with the sol-gel composition;
- and
- heating the coated substrate to form a doped anatase titanium dioxide coating.
An antimicrobial coating, comprising:
- a substrate;
- a doped anatase titanium dioxide coating on a surface of said substrate.
A doped titanium dioxide coating having at least one of improved antimicrobial properties, improved self-cleaning properties, and improved hydrophilicity, wherein said doped titanium dioxide coating is made by:
- preparing a titanium dioxide sol-gel composition comprising at least one dopant;
- coating a substrate with the sol-gel composition;
- and
- heating the coated substrate to form a doped anatase titanium dioxide coating.
