Development of novel corrosion inhibitors is important for improving the anticorrosion of carbon steel because the serious carbon steel corrosion causes enormous economic losses to humankind. In this work, we demonstrated the novel organic functionalized Fe3O4 hybrid inhibitor for enhancing the anticorrosion performance of carbon steel. For this purpose, amino-Fe3O4 nano-spheres (NH2–Fe3O4) were prepared via solvothermal route, using FeCl3.6H2O as an iron source and 3-aminophenoxy-phthalonitrile as precursor. Then, the N,N-diethyl-3-amine methyl propionate (DM) was reacted with amino-Fe3O4 nano-spheres to produce the organic functionalized nano-Fe3O4 hybrid. The chemical composition and micro-structure of as-obtained organic functionalized Fe3O4 hybrid were characterized and confirmed by Fourier transform infrared, X-ray diffraction, and scanning electron microscopy. Furthermore, the anticorrosion performance of carbon steel by addition of organic functionalized nano-Fe3O4 inhibitor was investigated by AC impedance measurements and polarization curves. The research results showed that the organic functionalized nano-Fe3O4 exhibited enhanced inhibition effect for carbon steel, which can be used as a new type of carbon steel corrosion inhibitor.
