Title (EN) POLYMER POROUS FILM AND METHOD OF PRODUCING THE SAME
(FR) FILM DE POLYMÈRE POREUX ET SON PROCÉDÉ DE PRODUCTION
Abstract: front page image
(EN)Provided is a porous material excellent in heat insulating property, mechanical property, and surface properties (such as adhesiveness and abrasion property). The porous material is a polymer porous film of a single layer, including a first porosity size changing portion (613) formed of independent porosities each showing a gradual increase in porosity size across a region accounting for 10% or more of a film thickness from a first surface side (611) toward a second surface side (612).
(FR)L'invention porte sur un matériau poreux excellent en termes de propriété d'isolation thermique, de propriété mécanique et de propriétés de surface (telles que la propriété d'adhésivité et d'abrasion). Le matériau poreux est un film de polymère poreux monocouche, comprenant une première partie à changement de taille de la porosité (613) formée de porosités indépendantes présentant chacune une augmentation progressive de la taille de la porosité sur une région représentant 10 % ou plus d'une épaisseur de film d'un premier côté de surface (611) vers un second côté de surface (612).
