An improved slurry of a conductive polymer is provided. The slurry comprises a conductive polymer and a polyanion, wherein the polyanion is a copolymer comprising groups A, B, and C expressed in proportions of formula A, A x B y C z . Formula A, wherein A is polystyrene sulfonic acid or a salt of polystyrene sulfonate, and B and C separately represent polymerized units substituted with groups selected from -C In (O)OR 6 , R 6 is selected from the group consisting of -(CHR 17 ) b -R 18 . All other groups are specified. The conductive polymer has an average particle size of at least 1-10 microns or less. [Selection figure] None |
