(FR) ECRAN TACTILE ANTIMICROBIEN ET SON PROCEDE DE FABRICATION UTILISANT DU SILANE EN CRISTAUX LIQUIDES HOMEOTROPIQUES
Abstract
(EN)
An anti-microbial touch panel (10) includes a substrate (14); an active portion (15) on one surface of the substrate; and a homeotropic organosilane layer (22) deposited on the active portion for reducing survivability of microorganisms contacting the touch panel.
(FR)
L'invention concerne un écran tactile (10) antimicrobien comprenant un substrat (14); une zone active (15) sur l'une des faces dudit substrat, et une couche organosilane homéotropique (22) déposée sur la zone active afin de réduire la survivabilité de microorganismes en contact avec l'écran tactile.
