Conducting composites core layers of indium tin oxide (ITO) particles embedded in polypyrrole (PPy) were prepared by polymerization. The morphology, molecular structure and electrical property of the composites were characterized by X-ray diffraction, Fourier transform infrared, scanning electron microscope, thermogravimetric analysis and conductivity measurement methods. The results indicated the ITO combined with PPy by chemical bond energy not the physical combine. Electrical conductivity measurements on the samples pressed into pellets showed that the maximum conductivity attained 13.97 ± 0.05 S/cm for PPy/ITO composites, at ITO particle doping concentration of 50 wt%. The highest conductivity of PPy/ITO crossing-rod composites was 11.00 ± 0.05 S/cm, of which the content of ITO crossing-rod was 15 wt%. The PPy/ITO composites showed a higher conductivity by comparing with that of neat PPy.
