Mechanical and corrosion protection properties of the epoxy nanocomposite coatings depended on the dispersion of nanoparticles in epoxy matrix. To improve the dispersion of carbon nanotubes zinc oxide (CNT/ZnO) in epoxy matrix composites, clay nanofil8 (N8) was added. Fourier Transform Infrared (FTIR), X-ray diffraction (XRD) Field Emission Scanning Electron Microscope (FE-SEM) analyses show the distribution of CNT/ZnO and clay in epoxy matrix. The electrochemical impedance spectroscopy (EIS) was evaluated the anti-corrosion of epoxy nanocomposite coatings. The mechanical properties such as adhesion, impact and bending strength were also carried out. By using 0.25 % CNT/ZnO combined with 1 % N8 compound, the mechanical and corrosion protection behavior of epoxy composite coatings were improved. Keywords. Carbon nanotube, clay, nano CNT/ZnO, epoxy, nanocomposite, corrossion.Downloads
