  • POLYMERIC MATERIALS AND METHODS FOR SELECTIVE ION SEPARATION OR TRANSPORT
    Publication number: 20240131475
    Abstract: Membrane materials and methods are disclosed for selectively separating or transporting ions in liquid media. In embodiments, the membranes comprise cellulose acetate polymer films having high cation, monovalent/divalent, and/or Li+/Mg2+ selectivity. Systems and methods for use of such membranes, including the direct extraction of lithium (DLE) from natural brines and other resources, also are disclosed.

  • POLYMER COATINGS THAT RESIST ADSORPTION OF PROTEINS
    Publication number: 20130228520
    Abstract: The invention provides membranes useful for filtration of water and other liquids. The membrane may be a composite membrane having a polymer layer incorporating quaternary phosphonium or ammonium groups. The polymer layer may be resistant to protein adsorption in an aqueous environment. The membrane may also be a surface-modified membrane in which a polymer having quaternary phosphonium or ammonium groups is covalently attached to the membrane surface. Methods for making and using the membranes of the invention are also provided.
