Abstract：

A novel composite functional carbon membrane for gas separation is designed and prepared by incorporating TS-1 nanoparticles into the thermosetting resins PMDA-ODA. The effects of the content of the TS-1 and pyrolysis temperatures on the permeability and selectivity performance of the functional carbon membranes are studied. The synthesized membranes are also characterized with TG, FT-IR, TEM and XRD. Results show that the addition of the TS-1 nanoparticles influences the performance of the membranes a lot, especially to the absorbable gas CO2 whose permeability was increased most. The permeabilities of membranes doping with 20.wt% TS-1 and carbonized at 600℃ for pure gas CO2、H2、O2、N2、CH4 are 9087、8111、2017、426 and 357 Barrer(1 Barrer=10-10 cm3(STP)?cm?cm-2?s-1?cmHg-1 ) , respectively. When the membranes are carbonized in temperature above 700℃, the permeabilities of the membranes for all the gases exhibited a drastic drop, while the selectivities are much improved.
