Confined ionic liquids, ionogels

J. Le Bideau, B. Humbert, M. Bayle, C. Ewels

The confinement of ionic liquids allows the properties of ionic liquids to be exploited while benefiting from containment as a solid. The diffusion properties in the resulting nanoporous ionogels (the nanopores seen here as "inverse nanoobjects") are similar to those of liquids. Through the variation of the chemical and topological characteristics of many ionogels, we have broadened our understanding of the behavior at the interface between ionic liquids and host networks by examining the dynamics of the ions, their interactions with each other, as well as their interactions with the host network. We focus on the fundamental understanding of self-organization, anomalous diffusion and surface-liquid interaction in these nanoconfined environments, with technological implications (energy storage and optical devices).
