The present invention relates to a transparent carbon nanotube polymer composite conductive ink and a method for preparing the same. This conductive ink is composed of a modified carbon nanotube, a conductive polymer, a water-soluble polymer cosolvent, a polymer modifying aid, a surfactant, and deionized water. In addition, a uniform dispersion of the carbon nanotubes and the conductive polymer solution is realized by a solution mixing process technique, and the prepared ink has good stability and redispersibility. In the present invention, a fine electrode pattern can be created by an apparatus such as spin coating or ink jet printing at room temperature conditions, and there is a possibility that a fine electrode pattern can be created by a photoetching process. There is a possibility that an electrode pattern having a fine structure can be formed only once by using the conductive ink. This ink can be applied to ultra-transparent electrode materials in devices such as flexible OLED display devices, solar cells, liquid crystal displays, touch screen panels, etc., and is compatible with transparent polymer substrates and has strong adhesion. The service life of the flexible electrode is ensured. [Selection] Figure 2 |
