Abstract: There is provided a carbon capture mixed matrix membrane comprising: a polymeric support layer; and a carbon dioxide capture layer in contact with the polymeric support layer, the carbon dioxide capture layer comprising solid porous material with at least one carbon dioxide adsorption site, wherein the polymeric support layer comprises spatially ordered uniform sized pores. The polymeric support layer may be patterned by micro-molding, nanoimprinting, mold-based lithography or other suitable lithographic process. The carbon dioxide capture layer may comprise amine-functionalised material, metal-organic frameworks such as zeolite imidazolate framework 8 (ZIF-8) or copper benzene-1,3,5-tricarboxylate (Cu-BTC) which may or may not be amine modified. There is also provided a membrane module comprising at least one carbon capture mixed matrix membrane and a method of forming the carbon capture mixed matrix membrane.

Abstract: There is provided a method of forming a thin film through-hole membrane comprising: providing a patterning structure, the patterning structure comprising a patterning substrate, a sacrificial layer and a thin film; imprinting the thin film with a patterned mold to form a thin-film through-hole membrane; and contacting the patterning structure with water to dissolve the sacrificial layer, thereby releasing the thin film through-hole membrane from the patterning structure. There is also provided a hierarchical membrane comprising the thin film through-hole membrane prepared from the method.
