Electrochemical impedance spectroscopy investigation of chlorinated rubber-based coatings containing polyaniline as anticorrosion agent / A. F. Baldissera in Materials and corrosion, Vol. 61 N° 9 (Septembre 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 9 (Septembre 2010) . - pp. 790–801 Titre : Electrochemical impedance spectroscopy investigation of chlorinated rubber-based coatings containing polyaniline as anticorrosion agent Type de document : texte imprimé Auteurs : A. F. Baldissera, Auteur ; D. B. Freitas, Auteur ; C. A. Ferreira, Auteur Année de publication : 2011 Article en page(s) : pp. 790–801 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Chlorinated  rubber;  corrosion;  electrochemical  impedance  spectroscopy;  paint;  polyaniline Résumé : Corrosion protection of mild steel by a newly developed chlorinated rubber (CR)-based coating system containing the inherently conductive polymer polyaniline (PAni) as an anticorrosion agent was studied. The synthesis of PAni and preparation of CR-based paint containing this polymer are described herein. The corrosion behavior of mild steel samples coated with a CR resin, CR/PAni-EB (emeraldine base), CR/PAni-ES (emeraldine salt), and CR/DBSA-doped PAni were investigated in 3.5% NaCl solution. For this purpose, electrochemical impedance spectroscopy and corrosion potential versus time measurements were utilized. It was found that the addition of the two forms of PAni, doped and undoped, to the CR resin increased its corrosion protection efficiency.
