dc.description.abstract | In this study, a novel and extremely facile method for the synthesis of conducting polypyrrole (PPy) was achieved in aqueous solution. This radiolytic method is totally free of template and environmentally friendly compared with traditional chemical methods. According to ultraviolet-visible (UV-vis) spectroscopy and Fourier transform infrared (FTIR) spectroscopy analysis, pyrrole (Py) monomers were polymerized into PPy thanks to their oxidation by HO∙ radicals produced by the radiolysis of water when exposed to γ irradiation. The morphology of PPy was characterized by Cryo-transmission electron microscopy (Cryo-TEM) in aqueous solution and by scanning electron microscopy (SEM) after deposition. In an original way, high resolution atomic force microscopy, coupled with infrared nanospectroscopy, is used to probe the local chemical composition of PPy nanostructures. The results demonstrated that spherical and chaplet-like PPy nanostructures were formed by γ-radiolysis. Thermogravimetric analysis (TGA) and electronic conductivity measurements showed that radiosynthesized PPy had good thermal stability and an electrical conductivity higher than that of chemically synthesized PPy. |
