摘要：
Single-walled carbon nanotubes (SWNTs) were functionalized with amphiphilic octadecylamine (ODA), and the solubility of SWNTs in chloroform was largely enhanced. The surface pressure-area isotherm indicated good spreading properties of functionalized SWNTs. According to scanning electron microscopy (SEM) images, highly ordered in-plane orientation of SWNT films was achieved by Langmuir-Blodgett (LB) technique at room temperature. The distance between the aligned SWNTs decreased with increasing surface pressure. Homogeneous multilayers were obtained via layer-by-layer deposition. The current-voltage (W) characteristics of multilayer films were investigated, in which the SWNTs were aligned perpendicularly and parallel to the electrodes, respectively.
