A novel mixed matrix membrane (MMM) is devleoped by incorporating pyrene-tagged ionic liquid-functionalized reduced graphene oxide (PTIL-rGO) into a polymer matrix. The as-prepared MMMs can separate CO2 efficiently due to the simultaneous enhancement of diffusivity selectivity, solubility selectivity, and reacivity selectivity. The high-aspect ratio rGO in a polymer matrix is expected increase the length of the tortuous path of gas diffusion and generate a rigidified interface between the polymer matrix and fillers, enhancing the diffusivity selectivity, combined with excellent affinity for CO2 to enhance the solubility selectivity and reactivity selectivity of the ionic liquids. |
