Abstract In this study, seven amino acid-based poly(ionic liquid)s (AAPILs) such as poly(1-butyl-3-vinylimidazolium glycinate), P[VBIm][Gly], poly (1-butyl-3-vinylimidazolium alaninate), P[VBIm][Ala], poly(1-butyl-3-vinylimidazolium valinate), P[VBIm][Val], poly(1-butyl-3-vinylimidazolium prolinate) P[VBIm][Pro], poly(1-butyl-3-vinylimidazolium hisdinate), P[VBIm][His], poly(1-butyl-3-vinylimidazolium lysinate), P[VBIm][Lys], and poly(1-butyl-3-vinylimidazolium arginate), P[VBIm][Arg] have been synthesized, characterized, and their CO2 absorption capacities were investigated using quartz crystal microbalance (QCM) at temperature range 288.15–308.15 and pressures up to 5 bar. Based on the absorption mechanism, the reaction equilibrium thermodynamic model is applied to correlating the experimental CO2 absorption capacities. The reaction equilibrium constant and Henry’s law constant were calculated to evaluate the efficiency of the AAPILs for CO2 absorption. In the investigated AAPILs, the CO2 absorption capacity was as follows: P[VBIm][Arg] > P[VBIm][Lys] > P[VBIm][His] > P[VBIm][Pro] > P[VBIm][Gly] > P[VBIm][Val] > P[VBIm][Ala]. The accessibility of available more amine groups in AAPIL with arginate anion is the main factor for the high CO2 absorption capacity. Also, chemical absorption of CO2 via carbamate formation was corroborated by FT-IR spectroscopy.

Objective: A new poly(ionic liquid)(PIL), poly(p-vinylbenzyltriphenylphosphine hexafluorophosphate) (P[VBTPP][PF6]), was synthesized by quaternization, anion exchange reaction, and free radical polymerization. Then a series of the PIL were synthesized at different conditions. Methods: The specific heat capacity, glass-transition temperature and melting temperature of the synthesized PILs were measured by differential scanning calorimeter. The thermal conductivities of the PILs were measured by the laser flash analysis method. Results: Results showed that, under optimized synthesis conditions, P[VBTPP][PF6] as the thermal insulator had a high glass-transition temperature of 210.1°C, high melting point of 421.6°C, and a low thermal conductivity of 0.0920 W m-1 K-1 at 40.0°C (it was 0.105 W m-1 K-1 even at 180.0°C). The foamed sample exhibited much low thermal conductivity λ=0.0340 W m-1 K-1 at room temperature, which was comparable to a commercial polyurethane thermal insulating material although the latter had a much lower density. Conclusion: In addition, mixing the P[VBTPP][PF6] sample into polypropylene could obviously increase the Oxygen Index, revealing its efficient flame resistance. Therefore, P[VBTPP][PF6] is a potential thermal insulating material.
