Abstract

In order to combine the advantages of silica as an inorganic material (chemical resistance, optical properties) to that of polypyrrole as a conductive polymer one has attempted to obtain novel silica-polypyrrole composite particles by a newly improved technique consisting to in situ polymerization of adsorbed pyrrole into silica. The new synthesized material was characterized by FT-IR spectroscopy, Optical and Scanning Electron Microscopy and the ionic conductive properties were evaluated by Electrochemical Impedance Spectroscopy.
