MODIFICATION PROGRESS OF POLYMER MEMBRANES FOR GAS SEPARATION.

The research on polymer membranes for gas separation has surprisingly blossomed during recent decades. Many modification techniques have been developed to improve the separation properties of polymermembranes. In this review, we give a systematic summary of the main aspect of polymeric gas separation membranes related to their physical and chemical modification, and propose perspectives for the future developments.
