Abstract

L'invention concerne un nouveau type de membrane semi-perméable. La membrane possède une structure multicouche, de préférence 4 à 12 couches, chaque couche agissant comme tamis moléculaire d'un pouvoir de rétention moléculaire défini. Applications : procédés de séparation moléculaire, tels que l'ultrafiltration, la dialyse, l'électrodialyse, l'osmose inverse, la perméation gazeuse et la diffusion gazeuse.
