Patent ID: 8784692

Claim:
A stable colloid particle containing composition comprising a continuous liquid aqueous medium having dispersed therein a polydioxythiophene and at least one colloid-forming fluorinated polymeric acid, and further comprising an additional material selected from the group consisting of polymers, dyes, carbon nanotubes, metal nanowires, coating aids, organic and inorganic conductive inks and pastes, charge transport materials, crosslinking agents, and combinations thereof, wherein said polydioxythiophene has the structure: wherein: R 1 and R 1 ′ are each independently selected from hydrogen and alkyl having 1 to 4 carbon atoms, or R 1 and R 1 ′ taken together form an alkylene chain having 1 to 4 carbon atoms, which may optionally be substituted by alkyl or aromatic groups having 1 to 12 carbon atoms, or a 1,2-cyclohexylene radical, and n is greater than about 6; wherein the composition does not re-disperse in an aqueous medium after it has been dried.
