| 摘 要： | 碳纳米管阵列是一种通过自组织形成的有序碳纳米管集体,其中的碳纳米管垂直于基底排列起来.超顺排碳纳米管阵列是一种特殊的碳纳米管阵列,其独特之处在于可以直接抽出连续的碳纳米管薄膜.该碳管薄膜仅有几十纳米厚,既透明又导电,其中的碳管沿抽拉方向平行排列.如果让拉出的薄膜通过一挥发性溶剂,或者采用边拉边绞的方式,该碳管薄膜又可以收缩成长线.该收缩后的长线具有高的力学强度和杨氏模量,是电的良导体.这些连续的薄膜和长线,将纳米级的碳管变成宏观可操控的客体,将碳纳米管优异的物理化学性质带到各种宏观应用,打开了一条从纳米世界通向宏观应用之路.该文将介绍超顺排碳纳米管在宏观尺度的应用和基于超顺排碳纳米管的产品,如高分辨透射电子显微镜用碳纳米管微栅,透明柔性可拉伸的碳纳米管薄膜扬声器,碳纳米管触摸屏等.

| Abstract: | Carbon nanotube (CNT) array is a self-organized highly oriented structure, in which CNTs are vertically aligned on the substrate. Superaligned CNT array is a special kind of vertically aligned CNT array with the unique capability of being converted into pure CNT films or yarns simply by drawing in dry state. The as-converted CNT films are tens of nanometers in thickness, transparent, and highly conductive, with aligned CNTs parallel to the drawing direction. After passing through volatile solutions or being... |
