Electrochemical and Chemical Syntheses of the Hybrid Organic-Inorganic Electroactive Material formed by Phosphomolybdate and Polyaniline. Application as Cation-Insertion Electrodes

摘要

We report a hybrid organic-inorganic electroactive material composed of a conductingudpolyaniline matrix and the phosphomolybdate anion ([PMo12O40]3-) as the active inorganicudcomponent. The material can be prepared electrochemically as thin films or chemically inudthe bulk, in the absence of other competing anions. The phosphomolybdate anion is anchoredudwithin the polymer matrix and not exchanged upon reduction. The material presents goodudconductivity and electroactivity, and it represents an example of electrodes that can takeudadvantage of the electroactivity of zero-dimensional molecular species. A preliminaryudanalysis of the material as a cathode in reversible lithium batteries is discussed
