主权项

1. A method for capturing carbon dioxide from a gas stream, comprising:
feeding the gas stream through an imidazole-containing polymer membrane, wherein the polymer membrane is formed by polymerizing an imidazole monomer and optionally one or more additional monomers, wherein the imidazole monomer has the following structure:wherein:
R is a polymerizable group; and X, Y, and Z are each independently selected from the group consisting of hydrogen, halogen, hydroxyl, substituted or unsubstituted C1-20 alkyl, substituted or unsubstituted C2-20 alkenyl, substituted or unsubstituted C2-20 alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted amino, cyano, nitro, and CO2CH3.
