大阵列的自取向，多壁碳纳米管（MWNTs）已获得通过化学气相沉积。到目前为止，这是不可能的翻译这个想法的增长单壁纳米管（SWNTs），但我们在这里表明，定向生长的单壁纳米管之间的垂直排列的MWNT阵列可以实现由二茂铁和二甲苯的催化热解。多壁碳纳米管作为单壁碳纳米管的支撑结构，迫使它们像葡萄藤一样稳定地向上生长。垂直排列的单壁碳纳米管在大面积上的生长带来了在选择配置中探索其特性的可能性。(C)2001年美国物理学会。
Large arrays of self-oriented, multiwalled carbon nanotubes (MWNTs) have been obtained by chemical vapor deposition. It has so far been impossible to translate this idea for growing single walled nanotubes (SWNTs) but we show here that oriented growth of SWNTs among vertically aligned MWNT arrays can be realized by the catalytic pyrolysis of ferrocene and xylene. The MWNTs act as the support structures for SWNTs, forcing them to grow upward steadily, like grapevines. The growth of vertically aligned SWNT over large areas brings about the possibility of exploring their properties in select configurations. (C) 2001 American Institute of Physics.
