文摘

Polyimide/functionalized MWCNTs MMMs were made via in-situ polymerization. In-situ prepared composites demonstrated the better carbon nanotubes dispersion. Functionalized MWCNTs improved the CO2 separation selectivity significantly. The functionalized MWCNTs MMMs demonstrated increased thermal stability.
