摘要

Penetrant-induced plasticization of gas separation membranes has been the subject of a number of recent investigation. The plasticization of the polymer matrix by penetrant gases can be attributed to the swelling stresses on the polymer network. It is well known that sorption of carbon dioxide in glassy polymers can facilitate the local segmental organization with a reduction in the permselectivity and substantially affect membrane morphological performance. Hence, plasticization is a phenomenon that most frequently encountered in polymer-gas systems for commercial CO_2/CH_4 separation applications where the membranes are expose to high CO_2 concentration in the feed strem. This paper attempts to present an overview of the plasticization phenomenon and the alteration of physical properties resulting from the polymer plasticization by the sorbed penetrant molecules. The plasticization suppression methods in polymeric membrane for gas separation and the future direction of research in this area are also given.
