Published: with international search report (Art. 21(3)) 00 O O (54) Title: A METHOD OF SYNTHESIZING A WATER-DISPERSIBLE CONDUCTIVE POLYMERIC COMPOSITE (57) : A method of synthesizing a water-dispersible conductive polymeric composite comprising mixing an aqueous suspen- sion comprising optionally substituted azulene monomers and a dopant precursor such as polystyrene sulfonic acid with an oxidiz- ing 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 sus pension 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.
