Abstract
L'invention concerne une membrane pour osmose inverse possédant de très bonnes propriétés d'élimination d'urée, et son procédé de fabrication. La membrane est produite par polymérisation dans un plasma à haute fréquence, d'un monomère non saturé en présence d'azote gazeux. L'azote est incorporé dans la matière polymérisée, sous une forme combinée chimiquement L'invention s'applique notamment à la purification des eaux usées dans des missions spatiales, des sous-marins, etc.
