Preparation of Graphene Oxide/Polyaniline Nanocomposite with Assistance of Supercritical Carbon Dioxide for Supercapacitor Electrodes / Guiheng Xu in Industrial & engineering chemistry research, Vol. 51 N° 44 (Novembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 44 (Novembre 2012) . - pp. 14390-14398 Titre : Preparation of Graphene Oxide/Polyaniline Nanocomposite with Assistance of Supercritical Carbon Dioxide for Supercapacitor Electrodes Type de document : texte imprimé Auteurs : Guiheng Xu, Auteur ; Nan Wang, Auteur ; Junyi Wei, Auteur Année de publication : 2013 Article en page(s) : pp. 14390-14398 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Electrodes  Supercritical  state  Carbon  dioxide  Nanocomposite  Preparation Résumé : We report a facile strategy to prepare graphene oxide (GO)/polyaniline (PANI) nanocomposite by in situ polymerization with the assistance of supercritical carbon dioxide (SC CO2). The morphology and chemical structure of the synthesized samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), FT-IR, Raman, and UV—vis spectrophotometry. As a result, PANI nanoparticles uniformly cover the GO sheets with the help of SC CO2, and the formation mechanism is suggested. The morphologies of GO/PANI nanocomposites can be controlled through adjusting the concentration of aniline. The GO/PANI nanocomposite exhibits better specific capacitance and cycle stability than pure PANI and GO owing to the synergistic effect of GO and PANI nanoparticles, making it promising application in electrochemical devices.
