  • Anti-fouling coatings with star polymers for filtration membranes
    Patent number: 10695724
    Abstract: A porous membrane with a molecular weight cut-off (MWCO) greater than about 10 kDa, and a coating on at least a portion of a major surface of the porous membrane. The coating includes a star polymer having a hydrophobic core and hydrophilic arms, wherein the hydrophobic core contacts the porous membrane.
    Type: Grant
    Filed: February 20, 2018
    Date of Patent: June 30, 2020
    Assignee: International Business Machines Corporation
    Inventors: Geraud J. Dubois, Robert D. Miller, Young-Hye Na, Victoria Piunova, Joseph Sly, Andy T. Tek, Ran Wang
  • Antifouling and antimicrobial coatings for thin film composite membranes
    Patent number: 10293308
    Abstract: A coated, thin-film composite membrane includes a porous support and a polyamide barrier layer in contact with the porous support. A fouling-resistant and antimicrobial layer of star polymers is in contact with the polyamide barrier layer. The star polymers included hydrophilic arms of about 40 mol % to about 80 mol % of neutral hydrophilic moieties, and about 60 mol % to about 20 mol % of antimicrobial functional groups.
