Porous organic polymer as fillers for fabrication of defect-free PIM-1 based mixed matrix membranes with facilitating CO2-transfer chain

Amine modified porous organic polymer endows highly selective CO2 adsorption capacity and good interfacial compatibility with polymer matrix, which provides specific transfer chains for facilitating CO2 molecules separation in MMMs, thereby exhibits excellent CO2 permeability of 7730 barrer and selectivity of 45.9 and 36.4 for CO2/N2 and CO2/CH4 gas pairs.306
