摘要: Ionic liquids (ILs) exhibit behavior analogous to supercooled 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−]) E, the aim of discovering influence E on dynamic heterogeneity ILs. show more homogeneous increasing as indicated by non-Gaussian parameters and susceptibility. The is greater in direction than that perpendicular directions same E. Despite heterogeneity, only a small decoupling between diffusion relaxation observed
