“…80 wt% AAIL contents did not break under compression stress of more than 25 MPa (Fig. S6(a), ESI †), which is more than 25 Ɵmes higher than those previously reported for [P 4444 ][Pro]-based ion gels consisting of PVP and PDMAAm single networks prepared by our group 8 . During compression, no AAIL leakage from the gel network was observed as a consequence of good compatibility between PDMAAm and the AAILs.…”

“…For the fabrication of AAIL-based DN gels, the most important parameter is the compatibility between AAILs and the polymer networks. In a previous report, 8 we found that polyvinylpyrrolidone (PVP) and polydimethylacrylamide (PDMAAm) have good compatibility with several phosphonium-based AAILs. Because PVP and PDMAAm are neutral polymers, we adopted them as the second network of the AAIL-based DN ion gels.…”

“…8 The developed AAILbased membrane with 70 wt% of AAIL content prevented the blow-out of AAILs under pressurized condition up to 1 MPa because the strong interaction between the polymer network and the AAIL yielded large osmotic pressure of the AAIL-gels. In addition, the AAIL-gel membranes exhibited acceptable CO 2 separation potential, nearly analogous to that of AAIL-based SILMs.…”

“…The same research group mentioned that there is a little difference in the CO 2 solubility among the AAILs with a common trihexhyltetradecylphosphonium cation [15]. Because of the excellent CO 2 solubility, the AAILs were applied not only to absorbents but also as components for adsorbents and separation membranes [16][17][18][19]…”

This paper reports the CO 2 solubility, density, viscosity, and electrical conductivity for a kind of amino acid ionic liquids (AAILs), tetrabutylphosphonium L-prolinate ([P 4444 ][Pro]). The physical properties of [P 4444 ][Pro] showed the ordinary temperature dependency, i.e. the density and viscosity decreased and the electrical conductivity increased with a temperature rising. One mole of [P 4444 ][Pro] absorbed a 0.970 mole of CO 2 at atmospheric pressure of CO 2 and 333.2 K, and desorbed only ~17 % of the absorbed CO 2 at 393.2 K. NMR spectra revealed that a CO 2 molecule formed a complex with [Pro]-, and [P 4444 ] + had a little effect on the CO 2 absorption. The CO 2 solubility increased steeply at lower pressures of CO 2 < 0.1 MPa and very gradually in the higher pressure range from 0.1 to 6 MPa at 333.15 K. Other tetrabutylphosphonium AAILs with (S)-2-methylprolinate ([P 4444 ][MePro]) and glycinate ([P 4444 ][Gly]) showed the similar pressure dependencies. The contributions of physical and chemical absorptions to the total CO 2 solubility were analyzed to discuss the effect of anion on the high-pressure CO 2 solubility. [P 4444 ][Pro] and [P 4444 ][Gly] showed the higher physical and chemical CO 2 absorptions (in molarity scale) in the present AAILs, respectively.

Inorganic/Organic Double‐Network Gels Containing Ionic Liquids

Highly robust ion gels, termed double-network (DN) ion gels, composed of inorganic/organic interpenetrating networks and a large amount of ionic liquids (ILs), are fabricated. The DN ion gels with an 80 wt% IL content show extraordinarily high mechanical strength: more than 28 MPa of compressive fracture stress. In the DN ion gel preparation, a brittle inorganic network of physically bonded silica nanoparticles and a ductile organic network of polydimethylacrylamide (PDMAAm) are formed in the IL. Because of the different reaction mechanisms of the inorganic/organic networks, the DN ion gels can be formed by an easy and free-shapeable one-pot synthesis. They can be prepared in a controllable manner by manipulating the formation order of the inorganic and organic networks via not only multistep but also single-step processes. When silica particles form a network prior to the PDMAAm network formation, DN ion gels can be prepared. The brittle silica particle network in the DN ion gel, serving as sacrificial bonds, easily ruptures under loading to dissipate energy, while the ductile PDMAAm network maintains the shape of the material by the rubber elasticity. Given the reversible physical bonding between the silica particles, the DN ion gels exhibit a significant degree of self-recovery by annealing.
