Production of electrically conductive polypyrrole of enhanced stability by treating a liquid pyrrole with a solution of a strong oxidant, capable of oxidizing pyrrole to a pyrrole polymer, and oxidizing the pyrrole by such strong oxidant in the presence of a relatively large organic dopant anion, and precipitating a conductive polypyrrole. The strong oxidant, e.g., Fe.sup.3+ ion, and dopant anion, which can be an alkyl or aryl sulfonate, e.g., methylbenzenesulfonate, or a perfluorinated carboxylate, e.g., trifluoroacetate, anion, can be derived from a single compound, e.g., ##STR1## the anion serving as dopant for the polypyrrole.
通过将液态吡咯与一种强氧化剂的溶液处理,能够将吡咯氧化为吡咯聚合物并使其氧化,然后在相对较大的有机掺杂阴离子的存在下氧化吡咯,并沉淀出导电性聚吡咯,从而生产出增强稳定性的导电聚吡咯。强氧化剂,例如Fe.sup.3+离子,和掺杂阴离子,可以是烷基或芳基磺酸盐,例如甲基苯磺酸盐,或者是全氟羧酸盐,例如三氟乙酸盐,可以来自单一化合物,例如##STR1##,该阴离子作为聚吡咯的掺杂剂。
