چکیده انگلیسی
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 TiO2 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.
