Title (EN) THIN FILMS COVALENTLY BONDED TO CELLULOSE ESTER MEMBRANES AND METHODS OF MAKING THE SAME
(FR) FILMS MINCES LIÉS DE MANIÈRE COVALENTE À DES MEMBRANES D'ESTER DE CELLULOSE ET LEURS PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)Embodiments disclosed herein are directed to membranes for filtration, methods of manufacturing the same, and membrane modules incorporating the same. In an embodiment, a membrane is disclosed. The membrane includes a porous cellulose layer, a polyamide thin film layer bonded to the porous cellulose layer, and a fabric support layer that supports the porous cellulose layer and the polyamide thin film layer. The porous cellulose layer has a pore size of about 30 nm to about 500 nm at an exposed surface of the porous cellulose layer.
(FR)Des modes de réalisation de la présente invention concernent des membranes pour la filtration, leurs procédés de fabrication, et des modules de membrane les incorporant. Dans un mode de réalisation, l'invention concerne une membrane. La membrane comprend une couche de cellulose poreuse, une couche de film mince de polyamide liée à la couche de cellulose poreuse, et une couche de support de tissu qui supporte la couche de cellulose poreuse et la couche de film mince de polyamide. La couche de cellulose poreuse a une taille de pore d'environ 30 nm à environ 500 nm au niveau d'une surface exposée de la couche de cellulose poreuse.
