Abstract: A method of synthesizing a water-dispersible conductive polymeric composite comprising mixing an aqueous suspension comprising optionally substituted azulene monomers and a dopant precursor such as polystyrene sulfonic acid with an oxidizing agent and a catalyst to form a doped poly(azulene) suspension wherein the poly(azulene)/dopant molar ratio is 1 :1 to 1 :6. The doped poly(azulene) suspension is then contacted with acidic and basic resins to remove the oxidizing agent and catalyst. The resulting suspension is then filtered through a membrane such as polyvinylidene fluoride (PVDF) to afford a purified suspension comprising the water-dispersible conductive polymeric composite. A water-dispersible conductive polymeric composite comprising an optionally substituted poly(azulene) doped by a dopant such as polystyrene sulfonate wherein the poly(azulene)/dopant molar ratio is 1 :1 to 1 :6 is also disclosed.
