| 英文摘要 | a series of copolymer, poly(phthalazinone ether sulfone ketone)s (ppesks) with the sulfone over ketone unit (s/k) ratio varying from 20/80, 50/50 to 80/20, were used as precursors to prepare carbon membranes. the effects of chemical structure as s/k ratio of ppesks on the microstructure and gas separation performance of their derived carbon membranes were mainly investigated. the properties of ppesks were detected in terms of density, fractional free volume, char yield, interlayer distance and glass transition temperature. during the formation process of carbon membranes (i.e., stabilization and pyrolysis), the changes in functional groups, microstructural parameters and gas permeation were monitored by ftir, x-ray diffraction, tem and single gas permeation techniques. the results have shown that the microstructure and gas permeation of obtained carbon membranes are significantly affected by the s/k ratio in precursor ppesks. carbon membranes exhibit higher selectivity and lower permeability when prepared at low pyrolytic temperature (i.e., 650 degrees c and 800 degrees c) and from ppesks with s/k ratio equaling 50/50, followed with 20/80 and 80/20. as for carbon membranes prepared at high pyrolytic temperature (i.e., 950 degrees c), the selectivity order of them is well in accordance with s/k mole ratio in precursor ppesks: 20/80>50/50>80/20, and vice versa for permeability.
