| 摘 要： | 采用低能量离子束对碳纳米管进行轰击。 扫描电子显微镜测试表明，离子束轰击可以方便地去除碳纳米管中的杂质，拉曼光谱结果显示离子束轰击没有对碳纳米管造成明显损伤。 以尿素作为杂质添加到碳纳米管中，经离子束轰击后发现尿素消失，说明离子束对杂质的去除机制为其溅射效应。

| Abstract: | Ion beam bombardment was used to bombard the carbon nanotubes. Scanning electron microscopy photographs indicate that ion beam bombardment can eliminate the impurities conveniently. On the other hand, Raman spectra analysis results show that ion beam bombardment do not cause obvious damages on carbon nanotubes. Urea added to carbon nanotubes as an impurity disappears after being irradiating, indicating that the main mechanism of the impurities removal by ion beam is sputtering effect. |
