Abstract
Polypyrrole (PPy) and PPy/Titanium oxide (TiO2) nanocomposites have been synthesized by a chemical oxidative polymerization method at room temperature with various compositions (10, 15 and 20wt%) of TiO2 in PPy. The structural characterization is accomplished by X-ray diffraction and optical characterizations are made using Fourier transform spectroscopy, ultra-violet visible spectrophotometry, and photoluminescence spectroscopy. The morphology of these nanocomposites is studied with scanning electron micrograph. The photoconductivity properties of pure PPy and PPy/TiO2 nanocomposites such as growth and decay of photocurrent have been studied in detail
