Electric double layer is the local distribution of ions created at any liquid and solid interface. Because the thickness of the electric double layer is typically in nanometer scale and the size of nanospace is as the same order of magnitude as the thickness of electric double layer, the nanospace should be partially/totally filled with an electric double layer.Here, electrical impedance spectroscopy was used to comprehensively investigate how the ionic concentration and the volume of nanospace influence on the electrical properties of various ionic solutions in a nanochannel. The electkinetic properties and the thickness of electric double layer in the nanospace were determined to be dependent on the hydration diameter, mobility, and ionic strength of the various ion spices. The electric double layer overlaps under particular conditions, such as with a sufficiently narrow channels, and the qualitative properties of this were consistent with the Debye-Huckel-Onsager equation.

双电层是在任何液体和固体界面处产生的离子的局部分布。因为双电层的厚度通常为纳米级，并且纳米空间的尺寸与双电层的厚度为相同的数量级，所以纳米空间应该部分/全部填充有双电层。利用电阻抗谱（electrical impedance spectroscopy，简称e-AC）技术，全面研究了离子浓度和纳米空间体积对各种离子的电性能的影响。纳米通道中的溶液。的电动性能和双电层的厚度在纳米空间被确定为取决于各种离子香料的水合直径，流动性和离子强度。双电层在特定条件下重叠，例如具有足够窄的通道，并且这种定性性质与Debye-Huckel-Onsager方程一致。
