This work search introduce of a new alternative of organic coating without the presence of hazardous metals and replacement of commercial rectifiers used for protection of oxidized metals by the method of anodic protection. From this, was produced of a Smart Paint (SP), basically composed of a Paint Polyurethane Commercial (PPC) mixed with a 1% of binder de base PAni EB and plasticizer chemically inert 4-chloro-3-methylphenol. After, the SP and PPC were applied in plates of carbon steel, with the use of dip coat technique. SP was characterized by thermal analyzes and physicochemical beyond perform electrochemical tests of Cyclic Voltammetry (CV) and Open Circuit Potential (OCP), in aqueous solution 2 mol.L-1 H2SO4. The results obtained allow us to state that the application of the binder to the PPC not significantly alters their physicochemical properties, and that the binder adds the ability to induce the formation or maintenance of protective oxides in oxidized metals exposed to harsh environments.
