Abstract
To separate carbon dioxide from a flue gas, membranes for gas separation was fabricated from polystyrene-b-polybutadiene (SB) diblock copolymer blends with poly(phenylene oxide), PPO. SB diblock copolymer formed miscible blends with PPO in the experimental range (lower than or equal to 70 wt% PPO). When the blend contained PPO whose composition is in the range of 40-50 wt%, the discontinuous phase of polybutadiene block in SB diblock copolymer, was changed to discrete phase, while polystyrene blocks containing PPO was changed to the continuous phase. A sudden decrease of the gas permeability and a sudden increase of the gas selectivity was observed at these blend compositions. A gas separation membranes having excellent mechanical properties and exhibiting advantages in gas permeability and selectivity could be fabricated from blends containing more than 50 wt% PPO.
