Poly(ionic liquid)s as new materials for CO2 absorption
Abstract
A series of imidazolium‐based ionic liquid monomers and their corresponding polymers (poly(ionic liquid)s) were synthesized, and their CO 2 sorption was studied. The poly(ionic liquid)s had enhanced CO 2 sorption capacities and fast sorption/desorption rates compared with room temperature ionic liquids. The effects of the chemical structures, including the types of anion, cation, and backbone of the poly(ionic liquid)s on their CO 2 sorption have been discussed. In contrast to room temperature ionic liquids, the polymer with PF anions had the highest CO 2‐sorption capacity, while those with BF or Tf 2 N− anions had the same capacities. The CO 2 sorption and desorption of the polymers were fast and reversible, and the sorption was selective over H 2, N 2, and O 2. The measured Henry's constants of P[VBBI][BF 4] and P[MABI][BF 4] were 26.0 bar and 37.7 bar, which were lower than those of similar room temperature ionic liquids. The preliminary study of the mechanism indicated that the CO 2 sorption of the polymer particles was more absorption (the bulk) but less adsorption (the surface). © 2005 Wiley Periodicals, Inc.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
