  • A series asymmetric poly (ether sulfone) gas separation membranes were prepared by dry/wet phase inversion processes. The membrane formation processes include two main processes, the evaporation process was dynamically monitored with FTIR-ATR and the immersion process was dynamically photoed with optical microscope. The kinetic effect of the dry/wet phase inversion process on the morphology has been studied. It is concluded that two factors (convection evaporation and solvent/nonsolvent exchange rate) are important in controlling membrane morphology for gas separation.

Abstract: A series asymmetric poly (ether sulfone) gas separation membranes were prepared by dry/wet phase inversion processes. The membrane formation processes include two main processes, the evaporation process was dynamically monitored with FTIR-ATR and the immersion process was dynamically photoed with optical microscope. The kinetic effect of the dry/wet phase inversion process on the morphology has been studied. It is concluded that two factors (convection evaporation and solvent/nonsolvent exchange rate) are important in controlling membrane morphology for gas separation.
