本文选用不同基底和溶剂进行单壁碳纳米管（ SWNTs ）样品制备，采用原子力显微镜（ atomic force microscope， AFM）观察进行表征和观测。结果表明，溶剂和基底对样品制备十分重要，会直接影响AFM观测效果。以去离子水为溶剂进行样品分散时，SWNTs在石英、硅片和云母三种基底上都出现了不同程度的聚积和重叠，影响观测效果。而采用乙醇为溶剂，在石英或云母为基底进行成像时，均可获得质量良好的图像。选择云母作为基底，可以大大减少基底处理时间，制样方便快速，并且能够获得理想的观测效果。

Single-walled nanotubes ( SWNTs) were prepared by different solvent and substrates, and they were observed by atomic force microscope ( AFM) . Sample preparation significantly influences the observation effect, and the appropriate method can enhance the observation results. When SWNTs were dispersed by deionized water, they presented different degrees of accumulation and overlapping. While SWNTs were dispersed by ethanol on quartz or mica, they could obtain good AFM images. Thus, mica is an ideal substrate for its simple and easy sample preparation.
