This work presents the synthesis of Polypyrrole/TiO2 nanocomposites. This nanocomposites were synthesized in aqueous media by polymerization of pyrrole using FeCl3 as an oxidant in the presence of poly(vinyl pyrrolidone) (PVP) as a surfactant and TiO2 nanoparticles. The PPy/TiO2 nanocomposites were characterized in terms of their particle size, morphology and chemical structure. X-ray diffraction (XRD) and fourier transform infrared (FTIR) spectra were used to characterized the structure of the obtained polypyrrole/TiO2 nanocomposites. Also the morphology of products was characterized by using scanning electron microscope (SEM). The results indicate that, the morphology and particle size of products are dependent on the presence of surfactant and metallic oxide
