Color tailoring PEDOT:PSS films with polymeric additive

摘要

The present invention provides an aqueous composition, comprising (a) a conducting polymer selected from the group consisting of polyanilines, polypyroles, polythiophenes and polyphenylenes, (b) a polyacid and (c) a polymeric additive having hydroxyl functional groups, wherein the pH-value of the aqueous composition is ‰¤ 3.5. Advantageously, the composition can be transformed into transparent conductive films.
