Abstract
(EN)
An article comprising a flexible polymer substrate having two major surfaces, a surface layer comprising metal, metal oxide, silicon oxide, or combinations thereof disposed on at least one major surface of the flexible polymer substrate; and a coating disposed on at least one surface layer, wherein the coating comprises a fluorinated polymer bonded to the surface layer; wherein the fluorinated polymer has the following general formula (I), where n = 6 to 120; and where n = 6 to 120; and where m = 1 to 25 (R1); (R2); or where m = 1 to 25 (R3).
(FR)
L'invention concerne un article comprenant un substrat polymère flexible ayant deux surfaces principales, une couche de surface comprenant un métal, un oxyde métallique, un oxyde de silicium ou des combinaisons de ceux-ci disposée sur au moins une surface principale du substrat polymère flexible ; et un revêtement disposé sur au moins une couche de surface, le revêtement comprenant un polymère fluoré lié à la couche de surface ; le polymère fluoré ayant la formule générale suivante (I), dans laquelle n = 6 à 120 ; et dans laquelle n = 6 à 120 ; et dans laquelle m = 1 à 25 (R1) ; (R2) ; ou dans laquelle m = 1 à 25 (R3).
