“…For the separation of CO2 from CO2/N2 gas pair. Lee et al [203] [DCA] due to highly delocalized anions of IL [206], and low N2 bonding [207]. For the high permeability, it is mainly because of the flexible structure and CF3 groups of TNf2, which permit fast throughput [208].…”

“…Usually, modified or synthesized ILs can increase the CO2 solubility based on synergistic effect between CO2 and the IL [217]. For example, adding inorganic particles into ILs [203,212] or using different types of precursors to synthesize ILs [219]. For example, CO2 have high affinity to delocalized anions [220] and -CN group [205].…”

Combination of membrane processes and ionic liquids have received more and more attention in pollutants removal because it enhances separation efficiency but also broaden their research and application areas. This review provides a first and systematical summary on ionic liquids incorporate in membrane processes for VOCs or CO2 separation, including supported ionic liquid membranes (SILMs), ILs composite polymer membranes (ILPMs), ionic liquids composite mixed matrix membranes (ILMMMs), poly(ionic liquid)s membranes (PILMs), ionic liquid gel membranes (ILGMs), and ionic liquid membrane contactors (ILMCs).Moreover, a new concept, combination of the membrane separation processes and absorption processes of ionic liquids, is introduced. Those separation processes are described detailly and compared with other conventional processes. With their separation performances and the processes of regeneration, membrane contactor shows stronger competitive advantages and it has the potential to be a major process in VOCs and CO2 separation. The advantages and disadvantages posed by all present ionic liquid membrane processes are summarized. Finally, challenges and opportunities in ionic liquid membrane separation processes are identified and discussed.

“…When compared to the pure PEO membrane and the composite membrane, the permeability increased from 11.0 GPU up to 144 GPU and the selectivity improved from 6.5 to 30. In these researches, CrO 3 particles increased the solubility of CO 2 , while free imidazolium ions of BMIM + BF4 − enhanced CO 2 transport, increasing permeability and selectivity [ 24 ]. Furthermore, highly selective composite membranes for CO 2 were suggested using BMIM + BF 4 − and rod-shaped aluminum oxide [ 25 ].…”

Polymer composite membranes containing aniline were prepared for CO2/N2 separation. Aniline was selected for high separation performance as an additive containing both the benzene ring to interfere with gas transport and an amino group that could induce the accelerated transport of CO2 molecules. As a result, when aniline having both a benzene ring and an amino group was incorporated into polymer membranes, the selectivity was largely enhanced by the role of both gas barriers and CO2 carriers. Selective layers coated on the polysulfone were identified by scanning electron microscopy (SEM) images and the interaction with aniline in the polymer matrix was confirmed by FT-IR spectroscopy. The binding energy of oxygen in the polymer matrix was investigated by XPS, and the thermal stability of the composite membrane was confirmed by TGA.
