Title (EN) MEMBRANE LAMINATES AND METHODS FOR THEIR PREPARATION
(FR) MEMBRANES LAMINEES ET PROCEDE DE FABRICATION
Abstract: front page image
(EN)Novel membrane laminate structures having a hydrogel layer useful for osmotic distillations and methods of making. The method includes applying a solution or dispersion of a hydrophilic prepolymer onto one surface of a microporous hydrophobic membrane sheet or to the external surface of a microporous hollow fiber membrane, evaporating volatiles from the coating and then cross-linking the prepolymer.
(FR)L'invention concerne des membranes laminées comportant une couche d'hydrogel, utiles aux fins de distillation osmotique, et des procédés relatifs à la fabrication desdites membranes. Ce type de procédé consiste à appliquer une solution ou une dispersion de prépolymère hydrophile sur une surface de membrane microporeuse hydrophobe ou sur la surface externe d'une membrane microporeuse creuse à base de fibres, puis à laisser évaporer les matières volatiles depuis le revêtement obtenu avant d'engager la réticulation du prépolymère considéré.
