Abstract: |
Hybrid carbon membranes were prepared by using 4, 4'-diaminodiphenyl ether -3, 3 ', 4, 4'-benzophenone tetracarboxylic dianhydride (BTDA-ODA) polyimide as precursor ang graphene as dopant, via the processes of blending, membrane-forming, drying and pyrolysis. The TG, SEM, XRD, IR and gas permeation technique were respectively applied to characterize the thermal stability of precursor, and the morphology, microstructure, surface chemical moieties and separation performance of carbon membranes. The effects of graphene content on the microstructure and properties of carbon membrane were investigated. Results show that the introduction of graphene leads to the enhancement of thermal stability of precursors. The resultant hybrid carbon membranes have both excellent permeability and molecular sieving ability due to the fairly well compatibility between graphene and membrane matrix. The gas permeability of hybrid carbon membranes is respectively increased by 6.8 times for H2, 46 times for CO2 and 59 times for O2. When the amount of graphene is 0.5%, the hybrid carbon membranes reveal attractive gas separation performance commercially, i.e., CO2 permeability of 1236.7 Barrer and CO2/N2 selectivity of 24.1. |
