摘要：Imidazolium-functionalized polyethersulfone (ImPES), a material for CO2 separation, was successfully synthesized. Subsequently, a fixed-carrier composite membrane was prepared with ImPES as the active layer and Polypropylene (PP) micro-filtration membrane as the support layer. The effects of degree of Imidazolium (DIm), ImPES concentration, test temperature and pressure on the performance of the membrane were investigated. Measurements carried out with humid feed revealed the performance of ImPES/PP membrane was improved with the increase of DIm. ImPES/PP membrane sample of 64%DIm and 20%ImPES concentration showed a CO2 permeation rate of 23.92 GPU and a CO2/N2 ideal separation factor of 65.34 in the test conditions of 30℃ and 0.4MPa.
