Abstract
Official abstract text for this publication.
A transparent cover glass for applications such as, but not limited to, touch screen devices that embody antimicrobial properties that include s being antibacterial, antifungal, and antiviral. The antimicrobial glasses contain nanoparticles of Cu or Cu 2 O on the surface of the glass. The antimicrobial glasses can further have a fluorosilane coating or other coating on the surface to make the glasses easy-to-clean. Also, glass surfaces having an antibacterial or antimicrobial surfaces and a protective coating on the surface that do not inhibit the antibacterial or antimicrobial properties of the glass are described. The disclosure is further directed to methods of making such articles.
First claim
Opening claim text (preview).
We claim: 1. An antimicrobial glass article comprising a glass substrate and copper-containing nanoparticles on a surface of the glass, the copper-containing nanoparticles being selected from the group consisting of Cu 0 nanoparticles, Cu 2 O nanoparticles, and combinations thereof, wherein the glass has an antibacterial log reduction value ≧1 and an antiviral log reduction value ≧1, and wherein the glass is chemically strengthened. 2. The glass article ac…
