| description | A co-east film composite flat sheet membrane for gas separation and/or olefin/paraffin separation. The co-cast film composite flat sheet membrane comprises an asymmetric porous non-selective support layer and an asymmetric integrally skinned polyimide-containing selective layer on top of the asymmetric porous non-selective support layer. The asymmetric porous non-selective support layer comprises a non-polyimide polymer or a mixture of a non-polyimide polymer and a polyimide polymer. The top surface of the asymmetric integrally skinned polyimide-containing selective layer is cross-linked under UV radiation and has a hydrophobic fluoropolymer layer.
Une membrane en feuille plate composite de film comoulé pour la séparation de gaz et/ou la séparation d'oléfine et de paraffine. La membrane comprend une couche de support non sélective poreuse asymétrique et une couche sélective asymétrique contenant du polyimide intégralement lisse sur la couche de support non sélective. La couche de support non sélective comprend un polymère non polyimide ou un mélange de polymère non polyimide et de polymère polyimide. La surface supérieure de la couche sélective est réticulée sous rayonnement ultraviolet et comprend une couche de fluoropolymère hydrophobe. |
