Congratulations to Kacie, Marlene on their recent article in Macromolecular Rapid Communications:
Their Paper titled: “Exploring Phosphonium-Based Anion Exchange Polymers for Moisture Swing Direct Air Capture of Carbon Dioxide” investigates the performance and stability of innovative anion exchange polymers for direct air capture technology.
Key findings show that:
Methyl-substituted phosphonium polymers achieve the highest CO₂ capture capacity thanks to minimal steric hindrance and strong bicarbonate pairing.
Butyl-substituted ammonium polymers exhibit the highest stability, resisting degradation over five capture cycles.
Oxidative degradation is primarily driven by dynamic acid-base reactions during moisture swing cycles in air.
These insights provide valuable guidance for developing high-capacity, robust materials suited to advanced carbon capture processes.
