Cellulose Acetate-Ionic Liquid Blends as Potential Polymers for Efficient CO₂ Separation Membranes.

ABSTRACT: CO₂ capture, applied in CO₂ separation from natural gas or in CO₂/N₂ separation from power plant flue gas streams, is of great importance for technical, economic, and environmental reasons. The latter seems important because CO₂, as a greenhouse gas, is considered the main contributor to global warming. Using polymeric membranes for CO₂ separation presents several advantages, such as low energy demand, small equipment volume, and the absence of liquid waste. In this study, two ionic liquids (ILs) were used for the preparation of cellulose acetate (CA)-IL blend membranes for potential CO₂ capture applications, namely, 1-butyl-3-methylimidazolium hydrogen sulfate ([Bmim+][HSO4-]) and choline glycine ([Ch+]Gly-), as
