Polymer membrane-based gas separation has been attracting recent interest due to its 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 performance of the current polymers, including PIs, do not meet the requirement for the industrial applications. We report herein multi-block PIM-co-PIs as novel polymer membranes for gas separation. Synthesis, characterization and their properties including gas separation performance of various compositions of polyimides will be discussed in details. |
