“…44e). 184 Lai et al also prepared ZIF-8/styrene-ionic liquid polymerization hollow fibers, which were demonstrated to be beneficial for increasing the CO 2 permeance of membranes. This enhancement contributes to the characteristic of the pore size of 3.4 Å and transport pathway provided by ZIF-8 fillers.…”

“…When binary gases are fed on the membrane, competitive adsorption between CO 2 and N 2 takes place in PAF-1-CH 2 NH 2 -cPIM-1. [7,47] As a result, the permeability decreases and the selectivity concurrently increases compared to those of single (pure) gases (Entries 7-8, Table 1). As shown in Figure 7a and Table S7 (Supporting Information), PAF-1-CH 2 NH 2 -cPIM-1 outperforms relevant membranes by virtue of permeability and selectivity.…”

Functionalized porous aromatic frameworks (PAFs) are excellent candidate materials for hybrid membrane fabrication. However, tailoring PAFs for membrane CO2 separation with desirable performance is still a challenge. Here, facile fabrication of functional hybrid alkylamine‐modified PAF‐1 containing membranes with high compatibility for efficient CO2/N2 separation is reported. The methylamino groups are installed on PAF‐1 resulting in PAF‐1‐CH2NH2 that has a high surface area of over 1400 m2 g–1 and unique CO2 adsorption with CO2/N2 thermodynamic selectivity of over 1000. Amidation reaction is developed for PAF‐1‐CH2NH2 cross linking with cPIM‐1 (carboxylic polymer of intrinsic microporosity), giving a homogenous compatible membrane of PAF‐1‐CH2NH2—cPIM‐1 with outstanding CO2 permeability (≈10790 Barrer) and high CO2/N2 permselectivity (≈43). This membrane outperforms the counterparts derived from parent PAF‐1 and phenylamine PAF‐1 and possesses superior performance to other relevant membranes for CO2/N2 separation. Such a membrane can selectively and stably separate CO2 from N2 in a simulated flue gas mixture, demonstrating its huge potential in carbon capture.

“…9,10 Room-temperature ionic liquid (RTIL) was used to eradicate the IL loss issue as it has negligible vapor pressure, 11 and several authors have already reported the effectiveness of SILM for gas separation. 12,13 Another critical aspect that must be taken into consideration is the techno-economic analysis. There are concerns regarding the cost of SILM since it introduces IL into the structure of a membrane.…”

“…Meanwhile, SILM struggles with the loss of IL. The IL is typically immobilized in the porous support in several ways such as direct blending or soaking of the membrane in the IL solution where this process could take place for a long duration. , Room-temperature ionic liquid (RTIL) was used to eradicate the IL loss issue as it has negligible vapor pressure, and several authors have already reported the effectiveness of SILM for gas separation. , Another critical aspect that must be taken into consideration is the techno-economic analysis.

This study proposes the fabrication of metal–organic framework (MOF)-based supported ionic liquid membranes (SILMs) to separate CO2 selectively. This report consists of two main parts; the first part focuses on optimizing polyethersulfone/poly(dimethylsiloxane)/zeolitic imidazolate framework-L (PES/PDMS/ZIF-L) composite membrane fabrication to improve CO2 permeance and selectivity simultaneously. The optimization process was carried out by the Box–Behnken design (BBD). At the optimized conditions (4.70 wt % PDMS, 5 mm/s withdrawal speed, 73.5 s dipping time, and 1.5:1 ZIF-L:PDMS ratio), the composite membrane recorded 6.61 GPU of CO2 permeance. Furthermore, the CO2/N2 and CO2/CH4 selectivities were 20.20 and 6.19, respectively. The second part of this report focuses on developing the supported ionic liquid membrane (SILM) by altering the optimized PES/PDMS/ZIF-L membrane. The SILM fabricated in this study undergoes a distinct fabrication method where the ionic liquid ([BMIM][BF4]) was impregnated in the ZIF-L instead of the porous support. Such a fabrication method was attempted due to the flexible structure of ZIF-L as a response to heat and able to immobilize the IL. As a result, SILM performed effectively as the CO2 permeance increased to 9.96 GPU at CO2/N2 and CO2/CH4 selectivities of 44.97 and 30.77, respectively. It is hypothesized that the enhancement of performance was achieved due to the synergy between the ZIF-L and IL, as revealed in this article.
