This study focuses on the application and behavior of a new pentafunctional phosphoric polymeric architecture in a marine environment. Through experiments and simulations, it was found that the anticorrosive coating produced good results and the data were in agreement with theoretical predictions.
This work consists in applying and studying the new pentafunctional phosphoric polymeric architecture - pentaglycidyl ether pentaphenoxy phosphorus (PGEPPP) - on the behavior of its coating, in a marine environment. First, we applied the new macromolecular pentafunctional epoxide (PGEPPP) binder, crosslinked by methylene dianiline and formulated by a natural phosphate, to E24 carbon steel, in the presence of two formulations, F1 (PGEPPP/MDA) and F2 (PGEPPP/MDA/PN). Then, we have studied the behavior of the anticorrosive coating on the metal substrate, in 3.5% NaCl. Indeed, the gravimetric, stationary and transient electrochemical studies of the composite (PGEPPP/MDA/PN) are very interesting and reach maximum values which are equal to 94%, 95% and 91%, respectively. We then proceeded to the prediction of the quantum parameters of the new pentafunctional phosphorus epoxy resin; these parameters were calculated according to the method of the Theory of Functional Density (DFT), at the level of 6-311 G (d,p) basis sets. Finally, the results obtained by the Monte Carlo simulation are in very good agreement with the data of the DFT theory and with the experimental data.
