摘要：
A dispersively aligned carbon nanotube array has been achieved between metal electrodes by electric-field assisted manipulation of surface modified single-wall carbon nanotubes (SWCNTs). Surface modification of SWCNTs with octadecylamine (ODA) molecules creates well-dispersed SWCNT solutions and effectively obviates the entanglement between deposited SWCNTs. The alignment effect of SWCNTs is improved by aligning them with an ac electric field of high frequency in a high-volatility solvent. The good electrical contact between the aligned SWCNTs and the metal electrodes is obtained by adopting a UV-light radiation method for removing the grafted ODA on the aligned SWCNTs.
