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. Also disclosed are a variety of substrates or articles of manufacture coated with the mixtures of the present invention for use in various applications where a combination of high electrical conductivity, -excellent optical transparency and low temperature processing are important, such as electronic and optoelectronic devices.

Abstract:
Disclosed are n-type solvent-based conductive polymer compositions comprising at least one conductive polymer, an organic solvent system, at least one dendrimer, and optionally, at least one additive. These conductive polymers exhibit isotropic electronic and/or optoelectronic properties, high conductivity and transmittance, tunable charge mobility and excellent environmental stability. These conductive polymers are suitable for use in a myriad of applications, including electronic and optoelectronic components and devices. Also disclosed are methods, involving a solvent exchange process, for producing these n-type conductive compositions.
