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.
