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.
