Synthesis, characterization, optical and electrical properties of novel highly dendritic polythiophene nanocomposites with silver and/or gold

Novel highly dendritic polythiophene/gold PT/Au and polythiophene/silver PT/Ag nanocomposites have been successfully prepared. Polythiophene PT has been also prepared for comparison. The obtained polymers have been characterized via scanning electron microscopy SEM, transmission electron microscopy TEM, UV–Vis absorption spectroscopy, Fourier transform infrared spectroscopy FT-IR and thermo gravimetric analysis TGA. Optical as well as electrical properties have been also investigated. It was found that the highly dendritic structure of the nanocomposites resulted in high improvements in the optical and electrical properties for the nanocomposites rather than that of pure PT.
