PEDOT/PSS COMPOSITION CAPABLE OF REDUCING SURFACE RESISTANCE OF TRANSPARENT ELECTRODE BY ADDING A WATER-SOLUBLE CONDUCTIVE POLYMER AND A COMPATIBILIZER INTO PEDOT/PSS, AND A PEDOT/PSS FILM USING THE SAME

摘要

PURPOSE: A PEDOT/PSS composition is provided to have excellent flexibility, to have simple coating process, and to able to reduce surface resistance to 240-300 Ω/□, thereby suitable for a transparent electrode for display.;CONSTITUTION: A PEDOT/PSS composition comprises PEDOT/PSS, solvent, a compatibilizer, and a water-soluble conductive polymer. The comprised amount of the compatibilizer is 1-10 weight% based on total weight of the PEDOT/PSS composition. The comprised amount of the water soluble conductive polymer is 0.1-36 weight% based on total weight of the PEDOT/PSS composition. A PEDOT/PSS film comprises a base element, and a transparent electrode formed by coating the base element with the PEDOT/PSS composition, and drying the same. The compatibilizer comprises a monomer comprising one or more anionic functional groups or amine functional groups, an oligomer, or a polymer.;COPYRIGHT KIPO 2012
