Abstract

HSSISSOU, Rachid; BENZIDIA, Bouchra; HAJJAJI, Najat  and  ELHARFI, Ahmed. Elaboration, Electrochemical Investigation and morphological Study of the Coating Behavior  of a new Polymeric Polyepoxide Architecture: Crosslinked and Hybrid Decaglycidyl of Phosphorus Penta methylene Dianiline on E24 Carbon Steel in 3.5% NaCl. Port. Electrochim. Acta [online]. 2019, vol.37, n.3, pp.179-191. ISSN 0872-1904.  http://dx.doi.org/10.4152/pea.201903179.

We developed and applied in our work a new polyepoxide polymer, decaglycidyl phosphorus penta methylene dianiline, to study its coating behavior in a marine environment. Then, we tested the new crosslinked and formulated macromolecular binder (DGPMDAP), which is used as an anticorrosive coating on E24 carbon steel, in 3.5% NaCl. So as to evaluate and examine the DGPMDAP coating performance in the field of E24 carbon steel corrosion, we applied the different E1 (DGPMDAP/MDA) and E2 (DGPMDAP/MDA/PN) formulations on the metal substrate. The stationary and transient electrochemical studies are very interesting; and, in order to confirm the obtained results, we dispersed the charge of the natural phosphate that was incorporated in the E2 (DGPMDAP/MDA/PN) macromolecular matrix, through the use of a polarizing optical microscope.

Keywords : DGPMDAP; architecture; coating; crosslinking; formulation; carbon steel; electrochemical studies.
