Abstract
L'invention concerne un procédé de traitement d'une pellicule de matière polymère hydrophile, en particulier un copolymère greffé, consistant à immerger la pellicule, à une température supérieure à 80 degrés C, dans un milieu de traitement liquide capable de faire gonfler la matière polymère hydrophile. L'invention concerne également une pellicule réalisée par ce procédé, de propriétés améliorées en augmentant l'utilité dans de nombreux cas, tels que la réalisation de séparateurs d'accumulateurs.
