Key Words:
utilizing method, external force, crush, wash, purify, slender carbon nanotube
The present invention relates to one physical technological method of purifying slender carbon nanotube. The purifying process includes external force crushing, liquid phase dispersion, deposition, filtering and washing. By means of the characteristics of slender carbon nanotube, which is flexible, wear resistant and easy to flocculate and deposit in liquid phase, coarse carbon fiber and large carbon nanotube may be eliminated easily and nano carbon particle, fine amorphous carbon and other easy-to-suspend impurity may be eliminated. The said process has no damage to slender carbon nanotube and has high purification efficiency.
