NANOTECHNOLOGY CARBON NANOTUBES Carbon nanotubes (CNT) are honeycomb-structured fine tubes with a diameter of a few nanometres. By dispersing the agglomerated carbon nanotubes in powder form in an agitator bead mill, they can be separated and stabilized. This can take place in either water, solvent, oil or in other liquids like glycerine.
