Polymer membrane for separating carbon dioxide has been developed and attracted attention because of global warming. Among various polymer membranes materials, Polyimide (PI) has excellent thermal and mechanical properties, good chemical stability and high gas transport property. In this work, We improved permeability of membranes can be achieved by controlling solubility. we synthesized PI-PEG copolymer to improve solubility. Diamines containing durene group were used to obtain polyimide having the high FFV. Finally, chemical structure were investigated and PI-PEG copolymer membrane and then we prepared hollow fiber PI-PEG membrane through controlled various parameter. also we measured gas transport property of PI-PEG membrane. |
