Abstract
L'invention concerne des membranes, des procédés de fabrication des membranes, et des procédés d'utilisation des membranes. La membrane peut comprendre une couche de support ; et une couche de polymère sélective située (par exemple, enrobée) sur la couche de support. La couche polymère sélective peut comprendre une matrice polymère comprenant un polymère de polyguanidine. Facultativement, la matrice polymère peut en outre comprendre un polymère hydrophile, un polymère contenant une amine, ou une combinaison de ceux-ci. Dans certains modes de réalisation, la couche polymère sélective peut en outre comprendre un support mobile (par exemple, un support mobile à base de guanidine, un support mobile à base d'amine, ou une combinaison de ceux-ci) dispersés à l'intérieur de la matrice polymère. Facultativement, le polymère sélectif ultérieur peut en outre comprendre un éther philanthropique CO2, un oxyde de graphène, des nanotubes de carbone ou une combinaison de ceux-ci, dispersés dans la matrice polymère. Les membranes peuvent être utilisées pour séparer le dioxyde de carbone d'autres gaz, tels que l'hydrogène et/ou l'azote. L'invention concerne également des procédés de séparation de flux gazeux à l'aide des membranes décrites ici.
