A high-dispersion carbon nanotube composite conductive ink, consisting of modified carbon nanotubes, conductive polymeric material, and solvent; said modified carbon nanotubes being obtained from conventional carbon nanotubes that have been irradiated on a UV bench and then oxidized by a strong acid. Carbon nanotubes obtained via this process do not require, when preparing conductive composite ink, the addition of a surfactant to increase the dispersibility of the ink, such that the conductive layer obtained therefrom has good conductive properties, optical transmittance within the visible light range, and flexibility. The conductive properties of this flexible carbon nanotube polymeric transparent conductive film are world class, and the invention has good prospects for application.
