A series of ferrite spinel nanopigments doped with various elements were synthesized via a surfactant-assisted solvothermal method. Then, they were modified with 3-amino propyl trimethoxy silane (APTMS) and characterized by x-ray diffraction analysis, thermal gravimetric analysis, Fourier transform infrared spectroscopy, and energy dispersive x-ray spectroscopy. The unmodified and APTMS modified spinel nanopigments were incorporated into epoxy coatings and their inhibition properties were studied by electrochemical impedance spectroscopy and salt spray test. Results showed that the APTMS modified ZnFe2O4 nanopigment resulted in greater improvement of the barrier action and inhibitive properties of the epoxy coating than Fe3O4 nanopigment.
