Embodiment Construction

[0032] The present preferred embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Ranges can be expressed herein as starting from "about" one particular value, and / or ending "about" another particular value. When such a range is stated, another embodiment includes from the one particular value and / or to the other particular value. Similarly, when values ​​are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. It should also be understood that the endpoints of each range are meaningful in combination with the other endpoints as well as independently of the other endpoints.

[0033] In the following detailed description, for purposes of explanation and not limitation, exemplary embodiments illustrating specific details a...

Abstract

Described herein are antimicrobial articles having improved antimicrobial efficacy and antireflective properties. Further described are methods of making and using the improved articles. The antimicrobial articles generally include an antimicrobial element and an antireflective element. The antireflective element, in some cases, can be disposed directly on a glass, glass-ceramic or ceramic substrate and the antimicrobial element is disposed on the antireflective element. The article can exhibit a reflectance of about 4% or less (and less than 1% in some cases) in the range of about 425 nm to about 725 nm. Further, the article can be characterized with an antimicrobial efficacy by exhibiting at least a 2 log reduction in a concentration of at least staphylococcus aureus, enterobacter aerogenes, and pseudomonas aeruginosa bacteria under a modified EPA copper test protocol.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 213,220, filed September 2, 2015, upon which this application is based and incorporated by reference in its entirety . technical field [0003] The present disclosure generally relates to antimicrobial and antireflective coating structures and elements. More specifically, various embodiments described herein relate to glass, ceramic, or glass-ceramic articles having antimicrobial-antireflective coatings disposed thereon such that the coated articles exhibit improved antimicrobial efficacy and antireflective optics properties; also to methods of making and using the coated articles. Background technique [0004] Touch-activated or touch-interactive devices, such as screen surfaces (eg, surfaces of electronic devices that are activated by touching specific portions of the surface and have user interaction ...
