COMPOSITION OF CARBON NANOTUBE DISPERSION SOLUTION INCLUDING ACRYLIC WATER BORNE POLYMER AND TRANSPARENT CONDUCTIVE FILM USING THE SAME

摘要

PURPOSE: A manufacturing method of a transparent electrode is provided to provide a transparent electrode having strong adhesion to a substrate, while maintaining electrical properties of carbon nanotubes through an environment-friendly, cheap and simple process. CONSTITUTION: A manufacturing method of a transparent electrode comprises carbon nanotubes, a dispersant, and acrylic water-soluble polymer as active ingredients. A manufacturing method of a conductive transparent electrode comprises: a step of dispersing carbon nanotubes into a solvent containing a dispersant; a step of adding an acrylic aqueous polymer into the carbon nanotubes-dispersed solution; a step of coating a substrate with the mixed solution; a step of cleaning the substrate coated with the carbon nanotubes-acrylic aqueous polymer composite film, and drying the substrate; and a step of post-treating the dried substrate by using metal salt.
