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., Fe³⁺ 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.,
the anion serving as dopant for the polypyrrole.
用能将吡咯氧化成吡咯聚合物的强氧化剂溶液处理液态吡咯,并在相对较大的有机掺杂阴离子存在下用这种强氧化剂氧化吡咯,沉淀出导电聚吡咯,从而生产出稳定性更强的导电聚吡咯。 强氧化剂(如 Fe³⁺ 离子)和掺杂阴离子(可以是烷基或芳基磺酸盐,如甲基苯磺酸盐,或全氟羧酸盐,如三氟乙酸盐)可以来自单一化合物,如作为聚吡咯掺杂剂的阴离子。
