Abstract

See full text

This invention relates to a conductive polymeric ink composition, including 1) a PEDOT:PSS aqueous dispersion, 2) dimethyl sulfoxide, 3) a solvent, 4) a surfactant, and 5) a phosphate compound represented by Chemical Formula 1, and to a transparent electrode formed using the same. The use of this ink composition enables the formation of a conductive polymer thin film having superior coatability or processability, including jetting capability and spreadability on a substrate, and high transmittance and conductivity.
