Abstract
A process for the preparation of an antimicrobial coating solution includes the steps of: (i) mixing a chelating agent with titanium alkoxide and fluoroacetic acid; and (ii) adding an aqueous solution to the mixture from step (i). The antimicrobial coating is visible light activated and can be applied to surfaces and optionally heat treated to form a transparent layer on the surface.
Claims6
A coated substrate comprising:
- a substrate having a surface;
- and
- an F and Cu doped titania coating fused into the surface of the substrate;
- wherein the coating induces antimicrobial activity under visible light, UV light and in conditions of reduced light or darkness;
- and wherein an anatase phase of the titania remains present at temperatures above 1100° C.
