摘要：

Polypyrrole-tetracyanonickelate, PPy-Ni(CN)4, has been synthesized in thin-film form by electrochemical oxidation of pyrrole in aqueous or non-aqueous media. The room-temperature electrical conductivity of one of the films (122 S cm-1) is the highest reported to date for any PPy-metal anion system. The temperature dependence of the conductivity is consistent with the Mott variable-range hopping model. Some of the films show good stability in air at room temperature, their conductivity decreasing by less than 7% over 50 days.
