Influence of ZIF-95 on structure and gas separation properties of polyimide-based mixed matrix membranes

Abstract

Polymeric membranes, especially polyimide membranes, are widely preferred in gas separation processes due to their superior properties such as inherently high permeability, selectivity, and easy processing. Zeolitic imidazolate frames (ZIFs) are crystalline porous materials exhibiting some unique properties, such as tunable pore sizes, thermal and chemical stability.
