ABSTRACT:
A method for producing oxidant/dopant reagent solutions which comprises reacting a basic ferric carboxylate, preferably basic ferric acetate, with an alkyl or aryl sulfonic acid, e.g., benzenesulfonic acid, to produce the corresponding ferric sulfonate in solution. Oxidant/dopant solutions can also be prepared containing cupric or ceric sulfonates. The oxidant/dopant solution is employed in situ for reaction with a pyrrole to produce electrically conductive polypyrrole. A porous substrate, such as fiberglass cloth, can be dipped in the oxidant/dopant solution, dried and then treated with a pyrrole to produce an electrically conductive polypyrrole deposit in the interstices of the substrate.
