Ionic liquids under 1D nanometric confinement in CNT membranes: gigantic transport properties?
Under confinement inside 1.4 nm Carbon NanoTubes (CNT), water adopts a very specific geometry characterized by a linear configuration of a fraction of the molecules. This peculiar local structure induces unexpected dynamical effects at the macroscopic scale: when forced inside a CNT membrane, water is experimentally found to flow-up three orders of magnitude faster than predicted by the continuum hydrodynamics picture: this is water superlubricity. We propose to extend the results observed on water to the case of Ionic Liquids (IL). The IL will be confined in macroscopically oriented CNT membranes. This macroscopic orientation will make it possible to disentangle the radial and longitudinal (perpendicular and alongside the CNT axes respectively) contributions to the overall dynamics.
