摘要

Intense investigations of room temperature ionic liquids have revealed not only their advantages in a wide range of technological applications but also triggered scientific debates about charge distribution properties within the bulk and near the solid-liquid interfaces. While many observations report on an alternating charge layering {i.e., spatially extended decaying charge density oscillations), there are recent conjectures that ionic liquids bear similarity to dilute electrolytes. Using a modified Poisson-Nernst-Planck model for ionic liquids (after Bazant et al., Phys. Rev. Lett 2011,106, 046102), we show that both behaviors are fundamental properties of ionic liquids. The transition from the non-monotonic (oscillatory) to the monotonic structure of electrical diffuse layers appears to non-trivially depend on ionic density in the bulk, electrostatic correlation length, confinement and surface properties. Consequently, the results not only reconcile the empirical results but also provide a powerful methodology to gain insights into the nonlinear aspects of concentrated electrolytes.

Lett 2011,106，046102），我们证明这两种行为都是离子液体的基本特性。从电扩散层的非单调（振荡）到单调结构的过渡似乎非常不依赖于整体中的离子密度，静电相关长度，限制和表面性质。因此，结果不仅调和了经验结果，而且提供了一种强大的方法来深入了解浓电解质的非线性方面。
