Nanocomposites based on rutile-TiO2 and polyaniline

A polyaniline/rutile-TiO2 nanocomposite, with a conductivity of 0.5 S cm− 1 at 25 °C, was prepared by in-situ polymerization of aniline in the presence of rutile-TiO2 nanoparticles, and was characterized by Fourier-transform infrared spectra, wide-angle X-ray diffraction, transmission electron microscopy, conductivity and cyclic voltammetry, as well as thermogravimetric analysis. The introduction of conducting polyaniline (PANI), not only improved the conductivity of rutile-TiO2 nanoparticles, but also improved the dispersibility of rutile-TiO2 nanoparticles. It can potentially be used in commercial applications as fillers for antistatic and anticorrosion coatings.
