Title:
透明電極及び透明電極形成用透明導電性インク
Document Type and Number:
Japanese Patent JP6807995
Kind Code:
B2
Abstract:
Provided are a transparent electrode and a production method thereof, the transparent electrode using metal nanowires and/or metal nanotubes as conductive components, and showing favorable surface flatness, conductivity, and light transmittance. A transparent conductive ink is prepared by dispersing metal nanowires and/or metal nanotubes in a solution formed by dissolving a thermoset or thermoplastic binder resin having no fluidity within the range of 5 to 40° C. to a solvent, the content of the binder resin being 100 to 2500 parts by mass relative to 100 parts by mass of the metal nanowires and/or metal nanotubes. An electrode pattern having a desired shape is printed on a substrate with the transparent conductive ink, and pulsed light is irradiated to the printed electrode pattern, to thereby obtain a transparent electrode having a surface resistance of 0.1 to 500Ω/□ and a surface arithmetic average roughness Ra satisfying Ra≦5 nm.
