  • CO2-philic thin film composite membranes
    Patent number: 11285445
    Abstract: Embodiments of the present disclosure describe a copolymer composition comprising a polyether-based copolymer, wherein the copolymer dissolves in one or more of an alcohol and alcohol-water mixture. Embodiments of the present disclosure describe a thin-film composite membrane comprising a porous support and a selective layer comprising a polyether-based copolymer, wherein the polyether-based copolymer dissolves in one or more of an alcohol and alcohol-water mixture. Embodiments of the present disclosure describe a method of capturing one or more chemical species comprising contacting a thin-film composite membrane with a fluid composition, wherein the fluid composition includes at least CO2 and capturing CO2 from the fluid composition. Embodiments of the present disclosure also describe methods of synthesizing copolymer compositions and methods of fabricating composite membranes.
