论文摘要
一维限制中电荷的静电筛选会导致纳米孔内的电反量远程分解。通过一系列连续模拟,我们证明了在一维限制中电解质的电压分解的原理。我们展示了膜中的相互作用孔如何抵消电击崩溃的现象,最终恢复到电击。重点放在应用简化公式以将多维偏微分方程减少到单个普通微分方程中,以获得静电势。独立研究了电解质和膜之间的介电不匹配,孔隙纵横比和限制维度,概述了纳米孔膜中电压分解在选择性离子传输和分离中的相关性。
The electrostatic screening of charge in one-dimensional confinement leads to long-range breakdown in electroneutrality within a nanopore. Through a series of continuum simulations, we demonstrate the principles of electroneutrality breakdown for electrolytes in one dimensional confinement. We show how interacting pores in a membrane can counteract the phenomenon of electroneutrality breakdown, eventually returning to electroneutrality. Emphasis is placed on applying simplifying formulas to reduce the multidimensional partial differential equations into a single ordinary differential equation for the electrostatic potential. Dielectric mismatch between the electrolyte and membrane, pore aspect ratio, and confinement dimensionality are studied independently, outlining the relevance of electroneutrality breakdown in nanoporous membranes for selective ion transport and separations.
