Abstract: |
|
Membrane materials of poly(ethylene oxide) (PEO) containing numbers of ether oxygen groups, which has favorable interaction with CO2, has high solubility selectivity of CO2/light gases resulting in high selectivity of CO2/light gases. The screenings of membrane materials with high solubility selectivity for separating CO2 was introduced. The development and gas separation properties of main PEO membrane materials were described emphatically. When the content of PEO reaches high enough, the PEO membrane materials have the almost closer solubility selectivity of CO2/light gases and different CO2 permeability because of the different chain structures of these membrane materials. |
