Title (EN) COMPOSITE STRUCTURE HAVING A FLUOROELASTOMERIC ANTI-REFLECTIVE COATING WITH NON-FLUORINATED CROSS-LINKING AGENT
(FR) STRUCTURE COMPOSITE DOTEE D'UN REVETEMENT FLUOROELASTOMERE ANTI-REFLET CONTENANT UN AGENT DE RETICULATION NON FLUORE
Abstract: front page image
(EN)Optical articles, such as displays, optical lenses, windows, optical polarizers and transparent films are made as a composite structure comprising a substrate and an anti-reflective coating applied to the substrate. The anti-reflective coating comprises: A) a fluoroelastomer having cures sites selected from the group consisting of bromine atoms, chlorine atoms, iodine atoms, non-conjugated dienes, and mixtures of two or more thereof; and B) a non-fluorinated multiolefinic cross linking agent. The surface of the substrate may be treated by simultaneously bombarding the surface with an ionized inert gas, and etching the surface with an ionized reactive gas, so as to improve the adhesion of the coating to the substrate.
(FR)L'invention concerne des articles optiques, notamment des écrans, des lentilles optiques, des fenêtres, des polariseurs optiques et des films transparents réalisés sous forme d'une structure composite comprenant un substrat et un revêtement anti-reflet appliqué sur le substrat. Le revêtement anti-reflet comprend : A) un fluoroélastomère doté de sites de polymérisation choisis parmi le groupe comprenant des atomes de brome, des atomes de chlore, des atomes d’iode, des diènes non conjugués et des mélanges de deux de ces substances ou plus ; et B) un agent de réticulation multioléfinique non fluoré. La surface du substrat peut être traitée en bombardant simultanément la surface avec un gaz inerte ionisé, et en gravant la surface avec un gaz réactif ionisé de sorte à améliorer l’adhésion du revêtement sur le substrat.
