A comprehensive review on PIM-1 membranes for enhanced CO(2) separation: strategies for CO(2) transport enhancement.

Modification strategies significantly improve CO2 permeability and selectivity in PIM-1 membranes, addressing the inherent trade-off and physical aging challenges.

• Why it matters: Efficient CO2 capture is crucial for mitigating climate change and achieving carbon neutrality, but current membranes face limitations in balancing permeability and selectivity.
• What they did: The review analyzes over various microscopic and macroscopic modification approaches, evaluating their impact on gas transport mechanisms and membrane performance.
• The result: Findings guide the design of next-generation PIM-1 membranes with enhanced CO2 separation capabilities, enabling more effective and durable carbon capture technologies.
