Abstract

This Concept examines strategies to design advanced polymers with high CO₂permeability and high CO₂/N₂selectivity, which are the key to the success of membrane technology for CO₂capture from fossil fuel-fired power plants. Specifically, polymers with enhanced CO₂solubility and thus CO₂/N₂selectivity are designed by incorporating CO₂-philic groups in polymers such as poly(ethylene oxide)-containing polymers and poly(ionic liquids); polymers with enhanced CO₂diffusivity and thus CO₂permeability are designed with contorted rigid polymer chains to obtain high free volume, such as polymers with intrinsic microporosity and thermally rearranged polymers. The underlying rationales for materials design are discussed and polymers with promising CO₂/N₂separation properties for CO₂capture from flue gas are highlighted.
