摘要：

Sulfonated polyaniline-titanium dioxide (SPAni-TiO2) hybrid composites have been synthesized by using a new strategy in one-pot system of UV-cured polymerization method. Aqueous solution of aniline and orthoanilinic acid comonomers, a free-radical oxidant and titania precursor were irradiated by UV rays, Hydrolysis and reprecipitation of the titania precursor in aqueous aniline and orthoanilic acid lead to the formation of titanium dioxide particles which in turn catalyze oxidation of comonomers to sulfonated polyaniline. The resultant SPAni-TiO2 composites were characterized by using different spectroscopy analyses like X-ray diffraction, UV-visible (UV-vis) and infrared spectroscopy. The UV-vis absorption hands revealed that SPAni-TiO2 nanocomposites are optically active and the blue-shifted peaks due to the presence of titania within the SPAni matrix. Scanning electron microscopy and transmission electron microscopy of the nanocomposite showed a uniform size distribution with spherical and granular morphology. Thermogravimetric analysis revealed that the SPAni-TiO2 composites have a good thermal stability than the pristine SPAni. (C) 2008 Elsevier B.V. All rights reserved.
