| Abstract: | Polypyrrole/ Silica nanocomposites were prepared by the in - situ chemical synthesis of polypyrrole in the presence of silica particles (10 - 20 run diameter) with water as solvent. These composites were characterized by a wide range of experimental techniques, including elemental microanalysis, infrared spectroscopy, thermogravime-try, transmission electron microscopy and four - point probe conductivity measurement. The tablets of the composite powder compressed under the pressure of 40 MPa possessed a conductivity up to 42.9 S/cm. |
