Polymer membrane-based gas separation have attracted recent interest due to their ease of operation and low operational cost. Polyimides (PIs) are the most widely used polymers for this application due to their toughness and moderate gas separation properties. However, the gas separation of the current polymers, including PIs, do not meet the requirement for the industrial applications in gas separation. We report herein novel polymers based on PIM-PI copolymeric strcture. Various types of PIM-PIs with different PIM compositions were prepared, and their properties including gas separation properties will be discussed in detail. |
