Title: Polymeric membranes for separation of gases

Abstract

Membranes, methods of making the membranes, and methods of using the membranes are described herein. The membranes can comprise a gas permeable support layer, optionally an inorganic layer disposed on the support, and a selective polymer layer disposed on the inorganic layer. In some cases, the selective polymer layer can comprise an amine-containing polymer and an amino acid salt dispersed within the amine-containing polymer. In other cases, the selective polymer layer comprises a sterically hindered amine-containing polymer, such as a sterically hindered derivative of polyvinylamine. The membranes can be used, for example, to separate gaseous mixtures, such as flue gas.
