  • Method for preparing an asymmetric membrane
    Patent number: 11083999
    Abstract: The present invention provides a method for the preparation of an asymmetric membranes. More particularly, the new method relates to the use of a crosslinker contacted via vapour or liquid phase with the surface layer of a cast polymer film, followed by the immersion of said film in a coagulation bath. The formation of a crosslinked skin layer and the solidification of the membrane bulk can thus be decoupled in time.
    Type: Grant
    Filed: June 6, 2016
    Date of Patent: August 10, 2021
    Assignee: Katholieke Universiteit Leuven
    Inventors: Sanne Hermans, Ivo Vankelecom, Annelies Van Sieleghem

  • Solvent resistant thin film composite membrane and its preparation
    Patent number: 9943809
    Abstract: The present invention relates to improved methods for synthesis of thin film composite membranes by interfacial polymerization. More in particular, the method of the present invention comprises the impregnation of an ultrafiltration porous support membrane with an aqueous solution containing a polyfunctional nucleophilic monomer, and contacting the impregnated support membrane with a second largely water-immiscible solvent containing a polyfunctional epoxide monomer.

  • IMPROVED METHOD FOR SYNTHESIS OF POLYAMIDE COMPOSITE MEMBRANES
    Publication number: 20170341036
    Abstract: The present invention provides a method for the preparation of thin film composite (TFC) membranes, preferably solvent resistant TFC membranes, by interracial polymerization (IFP), more in particular solvent resistant TFC membranes wherein a thin PA-layer is deposited on a porous support membrane. Said method comprises the replacement of the aqueous and/or the organic solvent in the IFP method by an ionic liquid (IL) as solvent for the monomers which form said TFC membranes, to alter the top layer morphology, thickness and crosslinking degree.

  • Method for synthesis of thin film composite membranes
    Patent number: 9808768
    Abstract: The present invention relates to improved methods for the preparation of thin film composite membranes by interfacial polymerization, preferably (organic) solvent resistant thin film composite membranes. More in particular the method of the present invention allows for the preparation of thin film composite membranes wherein a thin film is deposited on a porous crosslinked support. Said method comprises the one step solidification, impregnation and crosslinking of the porous support through phase inversion by immersion of the cast membrane polymer film in an (aqueous) solvent comprising a polyfunctional monomers.
