Abstract
Two new polymides with aliphatic group were synthesized. The aims are to break through the limit which aromatic polyimide is primarily material as gas separation membrane in polyimide membrane materials, and to look for gas separation membrane materials with good permeability and selectivity. Meantime, the gas permeate behavior of the new polyimides was also discussed. The relationship between permeation and structure of membranes were discussed. A preliminary probe into the mechanism of CO2 and CH4 permeating through polyimide membrane was done.
