Ionic liquids (ILs) confined within nanostructures show non-ideal properties. Recently, we reported on the enhanced carbon dioxide solubility in encapsulated ILs within a fluoropolymer matrix. Here, we developed a new method based on quartz crystal microbalance (QCM) to measure the solubility of carbon dioxide, at medium pressures (up to 15 bar), for ILs confined in the polymeric domains. We systematically investigated the effect of the composition of IL/polymer mixture, pressure, temperature, and nanomaterials additive to the system to address the scientific question behind non-ideality of confined ILs. The results showed that by tailoring the material interfaces and creating interphase domains between the ILs and polymer, the gas solubility in these mixtures could be enhanced by 2 folds, demonstrating a synergistic effect from IL/polymer system in gas sorption.
