    Electrical Conductivity of Polyaniline-Silver Nanocomposites

  • Original language description

    We present a brief overview of the electrical properties of conductive composites containing silver and conducting polymer-polyaniline. Composites were produced by oxidation of aniline with silver nitrate in the presence of various acids playing the roleof doping agents. A semiconducting behaviour was observed under the threshold about 21-27 vol.% of silver in composite and a metallic one above. From the temperature dependence of conductivity several charge transport mechanisms were proposed to explainexperimental data with the most likely option of a superposition of the variable range hopping or the charging energy limited tunnelling model with the Arrhenius-like activated transport. An effect of dynamic vacuum on conductivity was discussed in terms of moisture removal and possible structural changes. The differences due to various dopants were found to be negligible.
