Amino acid based poly(ionic liquid) materials for CO2 capture: Effect of anion
Poly(ionic liquid) materials based on eight amino acids (arginine Arg, lysine Lys, histidine Hist, taurine Tau, proline Pro, serine Ser, alanine Ala and glycine Gly) have been synthesized and characterized as CO2 absorbers. Among the broad family studied, Lys was found to have the highest gravimetri...
