Resumen

In this work, the synthesis of reduced graphene oxide (rGO) and its incorporation into a hybrid organic-inorganic matrix is reported. The hybrid matrix was obtained from Bisphenol A diglycidyl Ether (DGEBA) and tetraethylorthosilicate (TEOS) as the organic and inorganic phase, respectively, up to have an optimal hybrid matrix (HYBRID) having both good adherence on steel surface and good microhardness. In addition, the rGO was added to HYBRID (HGO). DGEBA, HYBRID and HGO were used as coatings on the surface of different 1018 carbon steel coupons. The coupons were immersed in a H₂SO₄ solution, then electrochemistry impedance spectroscopy (EIS) measurements were carried out. The corrosion current density, the corrosion rates, and the inhibition efficiency were estimated. The results show that the addition of rGO to HYBRID contributes to obtain a coating with good corrosion protective properties.
