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.

Abstract: Provided herein are methods of making asymmetric membranes comprising a first layer and a second layer. The methods include preparing a polymeric solution comprising one or more polymers, casting the polymeric solution to form a polymeric film, contacting the polymeric film with a solvent comprising a crosslinker under conditions to form a first layer on the top of the film, wherein the first layer is dense and solvent resistant, and contacting the polymeric film having the dense, solvent-resistant first layer with a non-solvent solution under conditions that form a porous second layer on the bottom of the film.

Abstract: A structure, and methods of making the structure are provided in which the structure can include: a membrane having a first layer and a second layer, the first layer comprising polymer chains formed with coordination complexes with metal ions, and the second layer consisting of a porous support layer formed of polymer chains substantially, if not completely, lacking the presence of metal ions. The structure can be an asymmetric polymeric membrane containing a metal-rich layer as the first layer. In various embodiments the first layer can be a metal-rich dense layer. The first layer can include pores. The polymer chains of the first layer can be closely packed. The second layer can include a plurality of macro voids and can have an absence of the metal ions of the first layer.
