A method for improving adhesion between two adjacent layers of a laminate membrane includes annealing the laminate membrane at a temperature above a thermal transition temperature of at least one polymeric component of at least one of two adjacent layers for a time sufficient for the at least one polymeric component of at least one of the adjacent layers to partially diffuse into the other adjacent layer. A sealed, inflated bladder of the invention prepared from the laminate membrane can experience high strains without layer separation or peeling of the laminate layers, even at a seam.
L'invention concerne un procédé d'amélioration d'adhérence interfaciale entre deux couches adjacentes d'une membrane stratifiée consistant à recuire la membrane stratifiée au dessus de la température de transition thermique d'au moins un composant polymère d'une des deux couches adjacentes pendant un temps suffisant pour que le composant polymère de cette couche diffuse partiellement dans l'autre couche adjacente. Une vessie étanche, gonflée, de la présente invention, préparée à partir de la membrane stratifiée peut subir des contraintes élevées sans séparation des couches ou de décollement des couches stratifiées, même à une jonction.
