Effect of external static electric fields on the dynamic heterogeneity of ionic liquids

Abstract:
Ionic liquids (ILs) exhibit behavior analogous to supercooled liquids at room or even higher temperatures. ILs usually work under an externally applied static electric field (E). In this work, molecular dynamics simulations were performed with 1-ethyl-3-methyl-imidazolium tetrafluorborate ([EMI+][BF4-]) under E, with the aim of discovering the influence of E on the dynamic heterogeneity of ILs. ILs show more homogeneous dynamics with increasing E, as indicated by non-Gaussian parameters and dynamic susceptibility. The dynamic heterogeneity is greater in the E direction than that in the perpendicular directions under the same E. Despite the dynamic heterogeneity, only a small decoupling between diffusion and relaxation is observed under E.

In the new picture, imagine that the first charge sets up an electric field independent of all other charges in the universe. When another charge comes in its vicinity, the second charge experiences an electric force depending on the electric field at that point. The source charge does not...

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
