摘要： A membrane is used for separating carbon dioxide from a gas phase. The membrane includes a substrate having micro-pores that extend through the substrate and a thin hydrophobic coating on one side of the substrate in which the pores of the substrate are substantially unobstructed by the coating so that the gas phase can penetrate the pores. The coating opposes or substantially resists a liquid solvent for absorbing carbon dioxide from penetrating the pores of the membrane from the side having the coating. The membrane may also be used for separating carbon dioxide in a flue gas of a coal fired power station. Further, the coating may be relatively inert to the liquid solvent compared to the substrate.
