A composite of polythiophene (PTh) and nanoscopic titanium dioxide (TiO2), possessing core-shell structure, was prepared via oxidative polymerization of thiophene by iron (III) chloride in the presence of TiO2 particles. The morphology of the obtained composite particles was studied by transmission electron microscopy, proving the core-shell structure of the prepared nanocomposite. The chemical structure of the composites was investigated by Raman spectroscopy.

Kompozit polythiofenu a nanočástic TiO2 se strukturou obal/jádro byl připraven oxidační polymerizací thiofenu chloridem železitým v přítomnosti částic TiO2. Morfologie získaných kompozitních částic byla studována pomocí TEM mikroskopie. Chemická struktura kompozitů byla studována pomocí Ramanovy spektroskopie.
