Dynamics in deep eutectic protic ionic liquid-DMSO mixtures
We propose to explore the relaxation processes occurring in deep eutectic binary mixtures of a protic ionic liquid (ethylamonium nitrate, EAN) and dimethyl sulfoxide. Similarly to water-DMSO, EAN and DMSO form mixtures with much lower melting point than the pure compounds. EAN and water have in common the extensive H-bonding network and its interaction with DMSO is presumably responsible for the peculiar thermodynamic behaviour. Complementing structural (high energy x-ray and neutron scattering) and other dielectric spectroscopic characterization, we propose to use backscattering QENS technique to access the mesoscopic local and diffusive dynamics of the two components.
