Abstract:
We report herein that self-organized subnanoporous membranes prepared from ionic liquid-crystalline (LC) compounds exhibit CO2 separation properties (αCO2/N2 ≈ 60) in humid conditions. A bicontinuous cubic (Cubbi) LC film shows N2 barrier properties, whereas the CO2 permeability is kept as permeable.
