Abstract
The invention relates to a method for self-assembling carbon nano tubes in water by regulating the temperature to guide polymer to modify the carbon nano tubes. The method comprises the following steps: adsorbing the polymer onto the surfaces of the carbon nano tubes; then dispersing the carbon nano tubes to which the polymer is adsorbed into the water; changing the temperature to enable the carbon nano tubes to be self-assembled in a solvent; and standing or centrifuging to separate a carbon nano tube self-assembling body. The self-assembling body is a carbon nano tube beam with a regular appearance and is formed by tightly arranging tens of to thousands of highly oriented carbon nano tubes in parallel. Self-assembly can centralize and enlarge excellent performance of the carbon nano tubes in the axial direction and enables the carbon nano tubes to have a wider application prospect. The method has simple steps and is easy to realize; the self-assembling operation is carried out in the water; a toxic organic solvent is not used; and the method is more environmental-friendly.
