New water-based nanocapsules of poly(diallyldimethylammonium tetrafluoroborate)/ionic liquid for CO₂ capture.

ABSTRACT: Encapsulated ionic liquids as green solvents for CO₂ capture are reported in this work. We present a novel combination of water-based poly(ionic liquid) and imidazolium-based ionic liquids (Emim[X]). Poly(diallyldimethylammonium tetrafluoroborate)/Emim[X] capsules were developed for the first time using Nano Spray Dryer B-90. Capsules were characterized by FTIR, SEM/EDX, TEM, TGA, DSC, CO₂ sorption, and CO₂/N₂ selectivity, CO₂ sorption kinetic and recycling were also demonstrated. Comparing the capsules reported in this work, the combination of poly(diallyldimethylammonium tetrafluoroborate) and the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (P[DADMA]/BF₄) showed great potential for CO₂ capture and
