PDMS-based artificial lung membranes with enhanced permeation to overcome the bottleneck in CO2/O2 selectivity

Retarded O2 transport in Co2+-coordinated supramolecular polymer networks for membrane CO2/O2 separations

“…CO 2 /O 2 separations are of great interest for healthcare and industrial applications. For instance, artificial lungs for CO 2 and O 2 exchange are critical for blood oxygenation; 1,2 atmospheric CO 2 and O 2 compositions can be manipulated for storing and transporting vegetables and fruit to improve their shelf lifetime; 3 CO 2 capture from fossil fuel-derived flue gas has been proposed as a critical way to mitigate CO 2 emissions to the atmosphere, and the flue gas contains 4–16% O 2 that needs to be separated from CO 2 . 4,5 Membrane technology offers a cost- and energy-efficient approach for gas separations.…”
