Polymeric Gas Separation Membrances

Abstract

Synthetic gas separation membranes have developed tremendously since the first commercial system was introduced just 15 years ago. Factors affecting the permeabilities and selectivities of new “tailor‐made” membrane materials are discussed. For example, because the p ‐isomer is more rod‐like than the m ‐isomer chain shown in the figure, the resulting membranes have a higher permeability. magnified image
