Carbon molecular sieve (CMS) membranes containing alkali metal ions (Li + , Na + , and K + ) were prepared by the pyrolysis of metal-substituted sulfonated polyimide (M-SPI) precursors. We have determined the effect of substituted metal ions in the polymeric precursor on the gas separation performan

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
