摘要：

Polypyrrole (PPY)/Co3O4 nanocomposites (NCs) were synthesized by a facile in situ polymerization of pyrrole in the presence of Co3O4 nanoparticles which were obtained by a rheological phase reaction method. The structure and morphology of the as-prepared PPY/Co3O4 NCs were investigated by X-ray diffraction, Fourier transform infrared spectra, Raman spectra, scanning electron microscopy and transmission electron microscopy, which confirmed the formation of the nanocomposites and indicated some interactions between PPY chains and Co3O4 nanoparticles. Different PPY/Co3O4 ratios were selected in order to study conductive properties. The electrical conductivity measurements indicated that ac conductivity tended to remain constant up to about 10(7) Hz for all samples, and thereafter increased with frequency. The desired electrical properties of PPY/Co3O4 NCs can be modulated simply by controlling the contents of Co3O4 nanoparticles.
