We report a highly ordered intercalated hexagonal binary superlattice of hydrophilically functionalized single-walled carbon nanotubes (p-SWNTs) and surfactant (C12 E5 ) cylindrical micelles. When p-SWNTs (with a diameter slightly larger than that of the C12 E5 cylinders) were added to the hexagonally packed C12 E5 cylindrical-micellar system, p-SWNTs positioned themselves in such a way that the free-volume entropies for both p-SWNTs and C12 E5 cylinders were maximized, thus resulting in the intercalated hexagonal binary superlattice. In this binary superlattice, a hexagonal array of p-SWNTs is embedded in a honeycomb lattice of C12 E5 cylinders. The intercalated hexagonal binary superlattice can be highly aligned in one direction by an oscillatory shear field and remains aligned after the shear is removed.
我们报告了一种高度有序的亲水化功能化单壁碳纳米管（p-SWNTs）和表面活性剂（C12E5）圆柱胶束的插层六方二元超晶格。当 p-SWNTs（直径略大于 C12E5 圆柱的直径）被添加到六方排列的 C12E5 圆柱胶束系统中时，p-SWNTs 以这样的方式定位，即最大化了 p-SWNTs 和 C12E5 圆柱的自由体积熵，从而导致插层六方二元超晶格。在这种二元超晶格中，p-SWNTs 的六方阵列嵌入在 C12E5 圆柱的蜂窝晶格中。插层六方二元超晶格可以通过振荡剪切场在一个方向上高度取向，并在剪切去除后保持取向。
