Interlocking a synthesized polymer and bifunctional filler containing the same polymer's monomer for conformable hybrid membrane systems

Abstract

Extra high-performance MMMs were fabricated by embedding a bifunctional host/guest complex (Schiff base macrocyclic copper complex in the FAU super-cages of zeolite 13X) into the 6FDA-durene matrix and examined for CO2/light gas separation.

CO2 separation of a novel Ultem‐based mixed matrix membrane incorporated with Ni2+‐exchanged zeolite X

“…4. NaX zeolite reveals several diffraction peaks at (2θ) = 9°, 14.8°, 18°, 23°, 27°, 30 °, 35°, 40°, 47°, and 51° 80 . All of the emerged peaks for NaX zeolite are conserved after ion‐exchange treatment without the appearance of a new peak.…”

“All Polyimide” Mixed Matrix Membranes for High Performance Gas Separation

“…Table 4 further shows that the increase of diffusivity coefficient leads to the increase of permeability coefficient. As shown in Table 1, AP has the highest FFV and porosity among the three microporous PIs particles, which is beneficial to improve the diffusivity coefficient of the "all polyimide" MMMs [42]. The skeleton of AP form an interpenetrating network architecture, which might form a high-rate gas transport channel [15,43].…”

“…The CO 2 diffusion coefficient (D CO 2 ) deduced from S CO 2 also prove that diffusion behavior dominated the permeation [21] (Table 5).

“…However, 6FDA-Durene has higher CO 2 affinity coefficient than 5AP/6FDA-Durene. This is because the −CF 3 group on 6FDA dianhydride monomer unit [42] can lead to CO 2 dipole polarization. C H value of 10AP/6FDA-Durene decreased to 43.88 cm 3 •g −1 , which demonstrated the blockage of the micropores in the dispersed phase.…”

Pebax/MWCNTs‐NH2 mixed matrix membranes for enhanced CO2/N2 separation

“…For MMMs, there are a variety of options for inorganic fillers, such as carbon nanotubes (CNTs), 6–8,15–17 zeolites, 18,19 silicas, 20,21 and metal‐organic frameworks, 22 which have been studied and shown good separation performance. Recently, several elaborate overviews of the current status and future challenge of MMMs on carbon capture were reported, where the advanced materials used in MMMs were discussed in detail 23–26 .…”
