An efficient route is used to prepare poly(3,4-ethylenedioxythiophene)/silver nanocomposite by chemical oxidative polymerization of 3,4-ethylenedioxythiophene monomer in Ag colloidal medium through emulsion technique using iron (III) p-toluenesulfonate hexahydrate (Fe(OTs) 3 .6H 2 O) oxidant. Sodium dodecyl sulfate plays a dual role involving both as emulsifier of the polymerization medium and stabilizer of the simultaneously reduced Ag nanoparticles. To compare the results obtained, an Ag-unloaded PEDOT is also prepared analogously. The resulted samples are fully characterized by fourier transform infrared, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV/vis, and thermogravimetric analyses. No remarkable aggregation of Ag nanoparticles occurs during the polymerization reaction. Moreover, average particle size of the incorporated Ag is found to be <10 nm.
