Claim:
1. A method for uniform dispersion of single-wall carbon nanotubes, comprising the following steps: (1) Dispersing single-wall carbon nanotube powder in a low-boiling point alcohol or water or DMF, then placing into a UV bench for ultraviolet irradiation and oxidation; (2) After cleaning the carbon nanotubes in the UV bench, using a strong acid to carry out an oxidation reaction, then washing by centrifugation to remove the strong acid; and (3) After cleaning with strong acid in step (2), subjecting the single-wall carbon nanotubes to ethanol or water ultrasonic dispersion 2-3 times, washing by centrifugation, then dissolving in low-boiling point alcohol or water or DMF solution to obtain a single-wall carbon nanotube dispersion.
