Polypyrroles were prepared by the chemical polymerization of pyrrole using various combinations of Fe3+ oxidants and electrolytes. The morphology and yield of the resulting polymers were affected by the property of the electrolyte anion in the oxidative solution. The size of the particles of the resulting polymers was decreased by using a high-molecular-weight polymer anion as the electrolyte anion. Both the polymer anion and Cl− were incorporated as a dopant into the polypyrrole matrix during the chemical polymerization of pyrrole, using an aqueous solution containing both FeCl3 and the polymer anion. On the contrary, the polymer anion was effectively incorporated as a dopant into the polypyrrole matrix during the chemical polymerization of pyrrole, using an aqueous solution containing both Fe(OH)3 and the polymer acid. A novel type of chemical preparation of the polypyrrole-polymer anion composite using the Fe(OH)3 oxidant and the polymer acid was developed.
