  • Gas separation membranes from polymer-grafted nanoparticles
    Patent number: 12042779
    Abstract: Gas separation membranes as may be used in separating gaseous materials from one another and methods of forming the membranes are described. The separation membranes include polymer-grafted nanoparticles (GNPs) as a platform and a relatively small amount of free polymer. The free polymer and the polymer grafted to the nanoparticles have the same chemical structure and similar number average molecular weights. The gas separation membranes can exhibit high ideal selectivity and can be used in a variety of applications, such as carbon capture.
    Type: Grant
    Filed: April 7, 2020
    Date of Patent: July 23, 2024
    Assignees: University of South Carolina, Columbia University
    Inventors: Brian C. Benicewicz, Yucheng Huang, Connor R. Bilchak, Sanat K. Kumar
