Title (EN) WATER AND OIL REPELLENT POLYURETHANE FILM
(FR) FILM CONTINU DE POLYURETHANE REPOUSSANT L'EAU ET L'HUILE
Abstract: front page image
(EN)A hydrophilic polyurethane film having at least one surface coated with an organic polymer having pendant perfluoroalkylalkyl or perfluoroalkyl groups as side chains. The organic polymer imparts oleophobicity and hydrophobicity to the polyurethane film. The films have good water vapor transmission rate.
(FR)L'invention concerne un film de polyuréthane hydrophile présentant au moins une surface recouverte d'un polymère organique comportant des groupes pendants perfluoroalkylalkyles ou perfluoroalkyles en suspension. Le polymère organique confère une caractéristique d'oléophobie et d'hydrophobie au film de polyuréthane. Ces films présentent un degré élevé de transmission de la vapeur d'eau.
