[54] Title of the Invention: A Type of Carbon Nanotube Alcohol and Its Preparation Method
[57] Summary

This invention involves a type of carbon nanotube derivant (i.e., the carbon nanotube alcohol) and its preparation method. The carbon nanotube derivant described in this invention is a type of carbon nanotube with hydroxyl groups attached on its surface. The carbon atoms connecting the hydroxyl groups take up 5~50% of the total number of carbon atoms (preferably at 13~17%). In this invention, the carbon nanotube derivant is prepared in following steps: mix the multi-wall carbon nanotubes or the single-wall carbon nanotubes with the hydroxides of alkali metals or alkaline earth metals to allow reaction under some mechanical force, and after purifying the reaction products, said carbon nanotube alcohol is obtained. The carbon nanotube alcohol of this invention is characteristic of its solubility in water, which provides the basis for its future applications in biochemical and biomedicinal fields; In solid state, the carbon nanotube alcohol in this invention can assembly themselves to build properly arrayed structures, which may provide templates for the large-scale synthesis of nanophase materials.

  1. A type of carbon nanotube alcohol, which features that it’s a type of carbon nanotube with hydroxyl groups attached on its surface, and the carbon atoms connecting the hydroxyl groups take up 5~50% of the total number of carbon atoms.
  2. A type of carbon nanotube alcohol according to Claim 1, which features that: said carbon atoms connecting the hydroxyl groups take up 13~17% of the total number of carbon atoms.
  3. A type of carbon nanotube alcohol according to Claim 1 or 2, which features that: said carbon nanotube alcohol presents an arrayed structure in good order.
  4. A type of method for preparation of the carbon nanotube alcohol as described in Claim 1, which consists of following steps: mix the multi-wall carbon nanotubes or the single-wall carbon nanotubes with the hydroxides of alkali metals or alkaline earth metals to allow reaction under some mechanical force, and after purifying the reaction products, said carbon nanotube alcohol is obtained. In this process, said mechanical force can be grinding, ball milling or high-speed disintegration; the reaction time under such mechanical force is 0.5~5 hours; said hydroxides of alkali metals or alkaline earth metals can be potassium hydroxide, sodium hydroxide, barium hydroxide and calcium hydroxide; the weight ratio of multi-wall carbon nanotubes or the single-wall carbon nanotubes to the hydroxides of alkali metals or alkaline earth metals is 1:5 ~ 20.
  5. A type of preparation method according to Claim 4, which features that: said mechanical force is exposed by a high-speed disintegrator that vibrates at 600 rounds/min ~ 10000 rounds/min.
