  • Cross-linked polymeric membranes for carbon dioxide separation
    Patent number: 9873094
    Abstract: A membrane useful in gas separation, the membrane comprising a cross-linked polysiloxane structure having a cross-link density of about 0.1×10?5 mol/cm3 to about 6×10?5 mol/cm3, where, in particular embodiments, the cross-linked polysiloxane structure has the following general structure: wherein R1, R2, R3, R4, R5, and R6 are independently selected from hydrocarbon groups having at least 1 and up to 6 carbon atoms; A1 and A2 are independently selected from cyclic hydrocarbon groups; L1 and L2 are linking groups or covalent bonds; n is an integer of at least 1; r and s are independently selected from integers of at least 1; and p is an integer of at least 10. The invention also includes methods for making and using the above-described membranes for gas separation.
