Description	Polypyrrole–silver (PPy–Ag) composite particles were synthesized by an oxidation of pyrrole with mixture of ammonium peroxydisulfate and silver nitrate. The molecular structure of PPy was assessed by Fourier transform infrared spectroscopy while the presence and amount of Ag was confirmed by X-ray diffraction analysis and thermogravimetric analysis, respectively. The scanning electron microscopy further revealed that the incorporation of Ag into PPy did not change the particles size and shape. Although the Ag presented in the composite particles increased their conductivity in one order of magnitude, the electrorheological (ER) performance did not change significantly above 63 wt.% of Ag, which was still below the percolation, compared to that of pure PPy. Moreover, it appeared that this amount of Ag improved the compatibility of dispersed particles with silicone oil used as a carrier liquid in ER suspensions. Furthermore, a faster interfacial polarization of PPy–Ag composite particles was observed from dielectric spectra.
