The oxidation of aniline with silver nitrate yielded a composite of two conducting components, polyaniline and silver. The acceleration with 1 mol% of p-phenylenediamine is needed for efficient synthesis. The product displayed metallic conductivity below 180 K and semiconductor type above this temperature. As the result, the conductivity was the same at 100 and 300 K. The oxidation of p-phenylenediamine alone with silver nitrate also produced a conducting composite having the conductivity of 1,750 S/cm despite the assumed nonconductivity of poly(p-phenylenediamine). The present study demonstrates that all oxidations proceeded also in frozen reaction mixtures at −24 °C, i.e., in the solid state.
