Development of CO<sub>2</sub>-Selective Polyimide-Based Gas Separation Membranes Using Crown Ether and Polydimethylsiloxane
A series of CO<sub>2</sub>-selective polyimides (CE-PDMS-PI-x) was synthesized by copolymerizing crown ether diamine (trans-diamino-DB18C6) and PDMS-diamine with 4,4′-(hexafluoroisopropylidene) di-phthalic anhydride (6FDA) through the polycondensation reaction. The structural characteris...
