Size of pores or spacing among nano‐protrusions such as nanotubes on an electrode surface greatly affects diffusive, viscous, and dielectric phenomena of electrolyte through openings. In this study, a configurational study was conducted to examine the effect of spacing among the single‐walled carbon nanotubes on dielectric and viscous phenomena. Behavior of a polar liquid, acetonitrile, was investigated by molecular simulations at two low densities. Results show that viscosity of the liquid is greatly enhanced by interaction with closely packed tubes' bundle. In conjunction with such increase in viscosity, relaxation of dipoles takes longer times inside such closed packed bundle. Most importantly, spacing among the tubes with diameter D should be at about D/2 in a direction for better dielectric phenomena.

不太远，不太近：碳纳米管束的结构研究，以更好地介电现象

纳米突起（例如电极表面上的纳米管）之间的孔大小或间距会极大地影响电解质通过开口的扩散，粘性和介电现象。在这项研究中，进行了结构研究，以检查单壁碳纳米管之间的间距对介电和粘性现象的影响。通过分子模拟在两种低密度下研究了极性液体乙腈的行为。结果表明，通过与紧密堆积的管束相互作用，液体的粘度大大提高。伴随着这种粘度的增加，偶极子的松弛在这种封闭的填充束中需要更长的时间。最重要的是，在更好的介电现象的方向上，直径为D的管子之间的间距应约为D / 2。
