Abstract:
1. A method comprising: (a) providing an aqueous solution comprising at least one oxidant and/or at least one catalyst; (b) providing an aqueous dispersion comprising a colloid-forming polymeric acid; (c) combining the aqueous solution of the oxidant and/or catalyst with the aqueous dispersion of the colloid-forming polymeric acid, (d) adding thienothiophene monomer to the combined aqueous dispersion of step (c); (e) polymerizing the thienothiophene monomer containing dispersion to form a polymeric dispersion; (f) adjusting the pH of the polymer dispersion to a pH from about 3 to about 8; (g) forming a film from the dispersion; and, (h) annealing the film under an inert atmosphere wherein the film has a resistivity change ratio of less than 100:1 before and after annealing.
