Interface-controlled property adjustment in ionic liquid/inorganic hybrid materials — •Andreas Taubert — University of Potsdam

Ionic liquids (ILs) have classically been used as solvents, for extraction, and catalysis. Materials synthesis and the adjustment of the properties of IL/inorganic and IL/polymer hybrid materials (ionogels) by tuning the interaction between an IL and the host material have recently attracted growing interest.

The advantage of ILs is that, by virtue of the large number of available IL components, their properties such as ionic conductivity or phase behavior can be adjusted.

Among others, IL-based hybrid materials are attractive candidates, for example, as membranes in fuel cells or batteries, in hybrid magnetic materials, or in multiresponsive materials. In order to understand, control, adapt, and extend the application of ionogels, the parameters controlling the structure, thermodynamics, phase behavior, and transport properties within the ionogels must be known.

The presentation will highlight some recent approaches towards quantification of these and other properties and highlight new developments towards transport of protons and ions in these highly complex nanostructured materials that could be of relevance for, e.g., energy research.
