Title (EN) ANTIMICROBIAL-ANTIREFLECTIVE ARTICLES AND METHODS FOR MAKING THE SAME
(FR) ARTICLES ANTIMICROBIEN-ANTIREFLET ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) 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.
(FR) L'invention concerne des articles antimicrobiens présentant une efficacité antimicrobienne améliorée et des propriétés antireflet. L'invention concerne en outre des procédés de fabrication et d'utilisation des articles améliorés. Les articles antimicrobiens comprennent d'une manière générale un élément antimicrobien et un élément antireflet. L'élément antireflet, dans certains cas, peut être disposé directement sur un verre, une vitrocéramique ou un substrat de céramique et ledit élément antimicrobien est disposé sur l'élément antireflet. Ledit article peut présenter une réflectance inférieure à environ 4 % (et inférieure à 1 % dans certains cas) dans la plage d'environ 425 nm à environ 725 nm. En outre, l'article peut être caractérisé par une efficacité antimicrobienne en présentant une réduction d'au moins 2 logarithmes népériens dans une concentration d'au moins les bactéries du staphylocoque doré, d’Enterobacter aerogenes, et de Pseudomonas aeruginosa sous un sous protocole d'essai au cuivre de l'EPA modifié.
