Nanocomposites of polypyrrole dodecylbenzenesulfonate‐titanium dioxide have been prepared from a colloidal solution of titanium dioxide (TiO 2 ) nanoparticles. The DC conductivity of samples with different concentrations of TiO 2 has been investigated under dark and light. The doping effect of TiO 2 has been characterized and evaluated by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy, and X‐ray diffraction. TEM shows that TiO 2 nanoparticles have strong effects on the morphology of composites, and conductivity measurements show that the conductivity first increases and then decreases as the percentage of TiO 2 is increased in the composites exhibiting a maximum in conductivity at about 20 wt % of TiO 2 . © 2010 Wiley Periodicals, Inc.
