Abstract

Arrays of aligned carbon nanotubes formed by self-assembly on a Si (100) surface are described. The surface of a Si (100) wafer has been modified by reaction of hydride-terminated Si (100) with ethyl undecylenate to give ethyl undecanoate self-assembled monolayers (SAMs) which were linked by stable silicon-carbon covalent bonds. The ester terminus of the monolayer was converted to an alcohol whereupon shortened carbon nanotubes were covalently attached using carbodiimide coupling. The formation of the SAM and its subsequent modification with nanotubes has been followed using a series of techniques including X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), scanning electron microscopy (SEM), IR spectroscopy and cyclic voltammetry.

摘要

描述了通过自组装在硅（100）表面形成的排列碳纳米管阵列。硅（100）晶片的表面通过氢化物封端的硅（100）与十一碳烯酸乙酯反应进行了改性，得到了通过稳定的硅-碳共价键连接的十一烷酸乙酯自组装单分子层（SAMs）。单分子层的酯端基被转化为醇，随后使用碳二亚胺偶联将缩短的碳纳米管共价连接。使用包括X射线光电子能谱（XPS）、原子力显微镜（AFM）、扫描电子显微镜（SEM）、红外光谱（IR）和循环伏安法在内的一系列技术跟踪了SAM的形成及其随后用纳米管进行的改性。
