In this paper we present as a first step the synthesis of an epoxide resin hexafonctionnelle following two steps. During the first stage, we performed phosphorylation of diphenylamine ethylene, followed by a second stage, which has led us to change after a new hexafonctionnelle resin. The microscopic structural characterization has been confirmed using the Nuclear Magnetic Resonance (NMR) proton and phosphorus. The epoxy resin is then cured with methylene dianiline (MDA) (HGEDAPT / MDA) and deposited on the copper. Finally we studied the impact of this new coating hexafonctionnelle epoxy resin on copper in an aggressive environment of 3% NaCl. Thereafter, we conducted a new formulation by adding an inorganic filler (zinc) in the protective matrix E1 (HGEDAPT / MDA) and E2 (HGEDAPT / MDA / Zn). The stationary and transient electrochemical studies are very interesting the value of their stationary efficiencies are respectively 92% and 97% and transitional 93% and 98.5%.
Author Keywords: Epoxy hexafonctionnelle, substrate-copper coating, curing, curve potentiodynamic polarization and electrochemical impedance spectroscopy.

Abstract: (french)
Dans ce travail nous présentons dans un premier temps la synthèse d'une résine époxyde hexafonctionnelle suivant deux étapes. Durant la première étape, nous avons effectué la phosphorylation de l'éthylène dianiline, suivie d'une deuxième étape, qui nous a conduit après sa modification à une nouvelle résine hexafonctionnelle. La caractérisation structurale microscopique a été confirmée à l'aide de la Résonnance Magnétique Nucléaire (RMN) du proton et du phosphore. La résine époxyde obtenue est ensuite réticulée avec la méthylène dianiline (MDA), E1 (HGEDAPT/ MDA) est déposée sur le cuivre. Dans un deuxième temps nous avons étudié l'impact de revêtement de cette nouvelle résine époxyde hexafonctionnelle sur le cuivre dans un milieu agressif de NaCl 3%. Enfin, nous avons procédé à une nouvelle formulation en ajoutant une charge inorganique (le zinc) dans la matrice de protection E2 (HGEDAPT/MDA/Zn). Les études électrochimiques stationnaire et transitoire s'avèrent très intéressantes, vue la valeur de leur efficacité stationnaire qui est respectivement 92% et 97% et transitoire 93% et 98,5%.
