Dynamics of ionic liquids under confinement
The propensity of Ionic Liquids (IL) to self-organize in transient nanoscopic domains induces a low ionic conductivity at long time (ms) and large scale (micrometer). We propose to lift the detrimental effect by frustrating the formation of the IL nanometric domains using confinement of the IL within a controlled porous structure. While a prepeak around 0.2-0.4 Å-1 of the confined IL structure factor can be used to quantify (in situ and on line) the extent of the nanosegregation, we will focus on the measurement of the translational self-diffusion coefficient of the center-of-mass of the confined IL molecules. The parasitic quasi-elastic contribution(s) of the IL side-chains will be discarded by use of a specifically deuterated IL.
