Abstract

Titanium dioxide doped polyaniline has been prepared by in situ polymerization. TiO₂ nanoparticles with an average diameter about 20 nm were used as a dopant of polyaniline. The doping effect of TiO₂ was characterized and evaluated by scanning electron microscopy (SEM), Fourier transformation infrared spectroscopy (FT-IR), energy dispersive spectrometry (EDS) and electrical conductivity measurement. SEM study shows that TiO ₂ nanoparticles have a strong effect on the morphology of composites. The FT-IR spectra reveal that the interaction between TiO₂ and polyaniline (PANI) is primarily based on the formation of H-bonding. Electrical conductivity measurements indicate that the conductivity of composites at low TiO₂ content is much higher than that of neat PANI, while with the increasing contents of TiO₂, the conductivity shows an orderly decrease.
