  • Highly CO-permeable and selective polymer blend membrane and process for preparing the same
    Patent number: 11920027
    Abstract: A polymer blend membrane includes a polyether-based copolymer and a polyether polymerized in situ and has high permeability and high selectivity for carbon dioxide. In the polymer blend membrane, the free volume of the polyether-based copolymer is greatly increased, and the adsorption capacity for carbon dioxide is enhanced. Thus, it can have excellent mechanical properties and excellent permeability and selectivity for carbon dioxide.
    Type: Grant
    Filed: May 3, 2022
    Date of Patent: March 5, 2024
    Assignee: SOGANG UNIVERSITY RESEARCH & BUSINESS DEVELOPMENT FOUNDATION
    Inventors: Jong Suk Lee, Munsuk Seong, Heseong An, Ju Ho Shin
