Title
(EN) COMPOSITE FILM, METHOD OF MAKING THE SAME, AND ARTICLE INCLUDING THE SAME
(FR) FILM COMPOSITE, SON PROCÉDÉ DE FABRICATION ET ARTICLE COMPRENANT UN TEL FILM COMPOSITE
Abstract
(EN)
A composite film comprises first and second layers. The first layer comprises a first copolymer of monomers comprising tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, wherein the first copolymer contains at least 35 mole percent of vinylidene fluoride monomer units. The second layer is disposed on the first layer, and comprises a second copolymer comprising 50 to 83 weight percent of ethylene monomer units and at least 17 weight percent of alkyl (meth)acrylate monomer units represented by the formula (I) wherein R1 is H or methyl, and each R2 is independently an alkyl group having from 1 to 4 carbon atoms. Methods of making the composite film and articles including it are also disclosed.
(FR)
L’invention concerne un film composite comprenant des première et seconde couches. La première couche comprend un premier copolymère de monomères comprenant du tétrafluoroéthylène, de l'hexafluoropropylène et du fluorure de vinylidène, le premier copolymère contenant au moins 35 pour cent en moles de motifs monomères de fluorure de vinylidène. La seconde couche est disposée sur la première couche, et comprend un second copolymère comprenant de 50 à 83 pour cent en poids de motifs monomères d'éthylène et au moins 17 pour cent en poids de motifs monomères d'alkyle (méth)acrylate représenté par la formule (I), R1 représentant H ou méthyle, et chaque R2 représentant indépendamment un groupe alkyle comprenant de 1 à 4 atomes de carbone. L'invention concerne également des procédés de fabrication du film composite et des articles le comprenant.
