Abstract
Carbon molecular sieve (CMS) membranes are an advanced class of membrane materials useful for many different gas-pair separations. One drawback of CMS membranes, as with many membranes, is a tendency for performance to decrease over time, termed physical aging. This work sheds light on the physical mechanism controlling physical aging in polyimide-derived CMS membranes and explores several techniques to minimize the effects.
