Gas transport properties of poly(ether-b-amide) segmented block copolymers

Blending PPO‐based molecules with Pebax MH 1657 in membranes for gas separation

“…The XRD spectra for addition of L‐81 to Pebax are shown in Figure . Peaks can be observed at 19.9° and 23.85°, in good agreement with other work . Also here, it can be seen that the additives do not act as plasticizers nor spacers since the d ‐spacing does not readily change.…”

Controlling Microstructure–Transport Interplay in Poly(ether-block-amide) Multiblock Copolymer Gas Separation Membranes

“…No significant dependence of D on the concentration was observed for either the sorption or desorption of CO 2 . The D values are in the range of 3.6 ± 0.2 × 10 –8 cm 2 /s which is comparable to those reported in previous studies. , …”

Effects of the Morphology of the ZIF on the CO2 Separation Performance of MMMs

“…Neat Pebax 2533 has a CO 2 permeability of ∼220 Barrer with a CO 2 /N 2 separation factor of 26, in good agreement with previously reported values. − A clear increment in CO 2 permeability was observed with the addition of all ZIF fillers despite the difference in particle shapes. This enhancement may be explained by several factors.…”
