研究了单壁纳米管(SWCNT)与对三联苯(p-Terphenyl)分子的交互作用和束散现象.SWCNTs分别由电弧放电法和一氧化碳高压分解法(Hipco法)制备.比较了不同制备工艺及纯化处理后SWCNTs与p-Terphenyl交互作用及其束散程度.采用分光和显微镜等技术,探讨了SWCNTs及其与p-Terphenyl交互作用.应用X光能量消散(EDAX)技术,给出了纯化处理前后SWCNTs试样的元素分析.利用萤光分析和原子显微镜技术评估了SWCNTs交互作用及束散程度.研究显示:SWCNTs束散程度及其和p-Terphenyl交互作用的强弱与SWCNTs纯化程度有关.

The interaction and dispersion of single-walled carbon nanombe (SWCNT) bundles were investigated. SWCNTs were produced by arc discharge and by the high pressure decomposition of carbon monoxide (HiPco method), in the presence of the molecule p-terphenyl. The dispersion of SWCNT bundles and their interaction with p-terphenyl in their as-produced state and after purification were compared. A number of spectroscopic and microscopic techniques were used to probe the SWCNTs and their interaction with p-terpbenyl. X-ray energy dispersive analysis was used to give an elemental analysis of the SWCNT samples before and after purification. Fluorescence and atomic force microscopy are used as techniques to assess the degree of interaction and dispersion of the SWCNT bundles, Results show that the extent of bundle dispersion and the degree of interaction with p-terphenyl is related to the purity of the SWCNTs.
