“…In Figure , it shows that the pristine neat Pebax membranes have two broad peaks at 12° and 21°, and another narrow peak at 24° in XRD patterns. They are the diffractions of semicrystalline for the rigid segment of polyamide 6 (PA6) and the flexible segment of poly(ethylene oxide) (PEO), and the crystalline region of polyamide block via interchain hydrogen bonding . It is obvious that the diffraction peaks of NaY zeolite are at 6.1°, 18°, 22°, 24°, 28°, 30°, and 37° .…”

CO 2 -selective Pebax/NaY mixed matrix membranes (MMMs) were prepared by incorporating NaY zeolite into Pebax matrix. The morphology, chemical groups, thermal stability, and microstructure of the MMMs were investigated by scanning electron microscope, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction, respectively. The effects of zeolite loading amount, permeation temperature and pressure on the CO 2 /N 2 separation performance of the resultant membranes were studied. The as-prepared MMMs are much superior to the pristine Pebax membranes in terms of permeability and selectivity. The CO 2 permeability and CO 2 /N 2 selectivity can respectively reach to 131.8 Barrer and 130.8 for MMMs made by the starting materials containing 40 wt % NaY.

“…Here, the in-situ generated amorphous carbon served as a dual carbon support and protective system which prevented the tentative agglomeration of MgO nanocrystallites. Similarly, Jiang's team 101 decorated the GO stacks with Zn 2+ ions by using polydopamine coating and embedded them into PEBAX matrix. The zinc ions are known for building a reversible π-complexation with CO 2 which fasten the CO 2 migration (137.9 Barrer) across the GO with a reasonable selectivity (CO 2 /CH 4 = 30.6) due to the more tortuous diffusion pathways.…”

Graphene has been hailed as a revolutionary membrane material because of its many alluring features and the ease in their tunability. In specific to gas separation industry, the exceptional molecular transport, the possibility of fabricating membranes having thickness at a nanoscale range and the robust lattice structure that can withstand to the rigorous perforation methods render graphene to stand ahead of its contemporary materials. Moreover, its broad chemical tolerance and high mechanical strength facilitate the mass-production of membranes possessing macroscopic dimensions and their subsequent long-term operation under harsh environments. In this concise review, we complied and discussed the progress of gas-separation performance of graphene-based membranes with a prime focus on recent advancements in scalability, functionalization/modification along with the new manufacturing processes including the budding approaches through synthetic chemistry. The strategies implemented, the factors that influenced the membranes'performance and the corresponding transport mechanisms were highlighted in detail. In the end, we outlined the daunting challenges facing by these graphene-based membranes in realization of their prospects as well as the proposed measures for alleviating them.

“…Despite the limited effect on CO 2 permeability ( Table 5 ), a tremendous improvement of CO 2 /N 2 selectivity (from 65 to 91) was observed at 0.8 wt % loading, while increasing the mechanical properties simultaneously. The modification of GO nanoplates with Zn ions have also been reported to produce hybrid membrane using PEBAX as polymer phase [ 110 ]. Dopamine (DA) was used as initiator of the Zn linkage on the GO substrate surface by complexing with the catechol functional groups of DA with the metal ions.…”

Membrane technology has the potential to be an eco-friendly and energy-saving solution for the separation of CO2 from different gaseous streams due to the lower cost and the superior manufacturing features. However, the performances of membranes made of conventional polymers are limited by the trade-off between the permeability and selectivity. Improving the membrane performance through the addition of nanofillers within the polymer matrix offers a promising strategy to achieve superior separation performance. This review aims at providing a complete overview of the recent advances in nanocomposite membranes for enhanced CO2 separation. Nanofillers of various dimensions and properties are categorized and effects of nature and morphology of the 0D to 2D nanofillers in the corresponding nanocomposite membranes of different polymeric matrixes are discussed with regard to the CO2 permeation properties. Moreover, a comprehensive summary of the performance data of various nanocomposite membranes is presented. Finally, the advantages and challenges of various nanocomposite membranes are discussed and the future research and development opportunities are proposed.
