Carbon molecular sieve (CMS) membranes were prepared by pyrolysis of polyimides containing carboxylic acid groups, in order to investigate their permeation properties for He, CO 2 , O 2 and N 2 . The polyimides were synthesized with a varying number of carboxylic acid groups in the diamine. Wide-ang

We prepared polyetherimide (PEI) hollow fiber membranes using polyvinylpyrrolidones (PVP) with different molecular weights (PVP 10,000, PVP 40,000, and PVP 1,300,000) as additives for oil/water separation. Asymmetric hollow fiber membranes were fabricated by wet phase inversion technique from 25 wt
One of the common polyimides, benzophenone tetracarboxylic dianhydride (BTDA)-4,4 -oxydianiline (ODA) polyimide, containing a ketone bridging group was synthesized to study the structural characteristics of the role of the polyimide on the properties of nanoporous carbon molecular sieve (CMS) membra
