Abstract

Amidoxime-functionalized polydimethylsiloxane (AO-PDMSPNB) membranes with various amidoxime compositions were synthesized via ring-opening metathesis polymerization followed by post-polymerization modification. Compared to other previously reported PDMS-based membranes, the amidoxime-functionalized membranes show enhanced CO₂permeability and CO₂/N₂selectivity. The overall gas separation performance (CO₂permeability 6800 Barrer; CO₂/N₂selectivity 19) of the highest performing membrane exceeds the Robeson upper bound line, and the excellent permeability of the copolymer itself provides great potential for real world applications where huge volumes of gases are separated. This paper details how tuning the CO₂-philicity within rubbery polymer matrices influences gas transport properties. Key parameters for tuning gas transport properties are discussed, and the experimental results show good consistency with theoretical calculations. This study provides a roadmap to enhancing gas separation performance in rubbery polymers by tuning gas solubility selectivity.
