Method for removing carbon impurities in single-walled carbon nanotube

摘要: The invention discloses a method for removing carbon impurities in single-walled nanotube. comprises the following steps: mechanically grinding; carrying out high-temperature hydrogen or medium-temperature plasma treatment; class screening on an air flow; and repeating steps two three times. According to method, mass fraction of nanotube, namely onion nanoparticles, multiwalled nanotube amorphous can be reduced from 50% below 0.05%. Meanwhile, as are fully treated by dry bulk structure maintained, thereby providing base applications such energy storage supercapacitor transparent conductive display. has advantages being less equipment, simple operate, easy repeat, process amplification low cost.
