Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 9 (Mai 2011) . - pp. 5589-5595 Titre : Preparation of polyaniline nanofibers by high gravity chemical oxidative polymerization Type de document : texte imprimé Auteurs : Xin-wei Lu, Auteur ; Wei Wu, Auteur ; Jian-feng Chen, Auteur Année de publication : 2011 Article en page(s) : pp. 5589-5595 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Polymerization  Oxidation  Preparation Résumé : To develop a suitable method for the mass production of polyaniline (PANI) nanofibers, the preparation of PANI nanofibers was carried out by high gravity chemical oxidative polymerization (HGCOP) in a rotating packed bed (RPB) for the first time. The influences of operating conditions, e.g., aniline concentration, high-gravity level, reaction temperature, and dopants, on the morphology of PANI nanofibers were investigated in detail. FTIR, UV―vis, XRD, molecular weight, and conductivity analyses were performed to characterize the products. Advantages of this new method are discussed. PANI nanofibers were successfully obtained in a wide range of aniline concentration (0.1―0.5 M) and reaction temperature (0―60 °C). The nanofibers kept small diameters of 30―50 nm and uniform morphology even when synthesized with a high initial aniline concentration of 0.5 M. This method provides a significant improvement to the rapid mixing route to prepare PANI nanofibers in large scale, moreover, it has potential applications in the synthesis of other conductive polymers.
