PIM-1 membranes containing POSS - graphene oxide for CO2 separation

Heteroatom-doped noble carbon-tailored mixed matrix membranes with ultrapermeability for efficient CO2 separation

“…38 More condensable CO 2 tends to occupy the Langmuir sites and reduces the permeability of N 2 and CH 4 . 49 The improved selectivity here also illustrates the preferential sorption of CO 2 in the PIM-1/C 2 N x O 1Àx -10 membrane and the excellent compatibility between PIM-1 and C 2 N x O 1Àx . 44,48 A possible gas transport workflow across the PIM-1/ C 2 N x O 1Àx membrane is schematically illustrated in Fig.…”

Thin film nanocomposite membranes of superglassy PIM-1 and amine-functionalised 2D fillers for gas separation

“…26 The above mentioned model has been broadly used for the prediction of permeation performance in MMMs and reported by our group for 2D fillers-containing membranes. 18,27…”

Outstanding performance of PIM-1 membranes towards the separation of fluorinated refrigerant gases

“…Despite their outstanding separation performance, PIM-1 membranes undergo physical aging, a reversible polymer chain rearrangement due to the relaxation of the non-equilibrium polymeric chains, which implies the loss of free volume (increase chain packing) and the decay of the permeability over time, this fact being the main constraint for their industrial application [26]. In this sense, great efforts have been expended to minimize or avoid the aging phenomenon of PIM membranes by techniques such as the incorporation of inorganic fillers to the PIM-1 matrix [21,27,28]. Moreover, the topology of the PIM-1 also influences both the separation properties and the rate of physical aging [29,30].…”
