The facile construction of an anion exchange membrane with 3D interconnected ionic nano-channels.

The co-organization of polymerizable imidazolium-based ionic liquids and p-xylene led to the formation of a bicontinuous cubic phase with a primitive-type periodic minimal surface, and for the first time an anion exchange membrane preserving 3D interconnected ionic nano-channels was fabricated through in-phase photopolymerization of bicontinuous cubic liquid crystals.
