  • Single-step synthesis of chemisorption fiber sorbents (CHEFS) for the capture of COand removal of water contaminants
    Patent number: 11738328
    Abstract: One or more embodiments relates to method for generating CHEFS having the steps of generating the CHEFS from a dope. One or more embodiments relates to a method for generating CHEFS having amine functional groups having the steps of generating a dope containing a BIAS with amine groups, at least one polymer, and at least one solvent; and forming CHEFS from the dope, wherein the generated CHEFS have no more than 30% amine loss compared to the BIAS.

  • Amidoxime Functionalized Polymers Loaded with Alkyl Amines, Methods of Making, And CO2 Capture Using Same
    Publication number: 20230056553
    Abstract: A novel adsorbent and contactor material based on polymer functionalized with amidoxime and alkylamines moieties. Methods of making the material are also described. The material can be easily processed into any desired sorbent geometry such as solid fibers, electrospun fibers, hollow fibers, monoliths, etc. The adsorbent exhibits a very high affinity toward acidic gases such CO2 and can be used in direct air capture, power plant-based CO2 capture, and industrial CO2 capture applications. The material can also serve as a contactor that accommodates other adsorbents within its structure.
