Abstract: Disclosed are mixtures comprising aqueous thiophene/anion dispersions, such as polythiophene/polystyrene sulfonate aqueous dispersions, and additives, as well as coatings produced therefrom. Coatings produced from these mixtures yield significant improvements in electrical conductivity without the need for a high temperature treatment as compared to coatings produced from unmodified aqueous polythiophene dispersions (e.g., Baytron®P) and to coatings produced from state-of the-art aqueous polythiophene-additive mixtures. These conductivity improvements are achieved without detracting from the optical transparency of the coating. Because characteristics of volume resistivity of less than 6.6 ohm·cm and optical transmission greater than 80% are important for conductive coating applications, coatings produced from the mixtures of the present invention have significant advantages over coatings produced from the state-of-the-art mixtures in many applications.

Abstract: Disclosed are coatings, films, and articles of manufacture comprising or derived from compositions that are produced by a method for exchanging solvent in a mixture that includes water and an optionally substituted thiophene. Also disclosed are methods for making and using said coatings, films, and articles of manufacture, including electro-optical implementations.

Abstract: Disclosed are compositions formed by a method for exchanging the water in an optionally substituted polythiophene dispersion with a specific mixture of organic solvents. The resulting compositions exhibit improved electrical conductivity, optical transparency, environmental stability, excellent adhesion to a variety of substrates and processing characteristics. Also disclosed are methods for making and using such compositions.
