1. A composition comprising:
- a combination of an aqueous dispersion of an optionally substituted poly-3,4 alkylene dioxythiophene cation and an associated polyanion; and
1% (w/v) to 100% (w/v) of one or more organic solvents, wherein the one or more organic solvents have a boiling point between from about 80°
C. to about 290°
C., wherein at least 30% (w/v) of the water from the aqueous dispersion is removed from said combination.
