Abstract: (31 Views)
The present study used a Metal-Organic Framework as an inhibitor carrier in epoxy anti-corrosion
coating. For this purpose, ZIF-8 was first synthesized, and then the synthesized structure was
characterized by XRD, FTIR, TGA, BET, and SEM analyses. Next, the Zinc Acetate inhibitor was
loaded into the ZIF-8 cavities. BET, TGA, and SEM analyses were used to confirm the loading, and
ICP analysis was used to investigate the inhibitor release pattern. Then, by adding ZIF-8 containing
inhibitor to the epoxy coating, applying the coating to steel sheets, and creating artificial scratches on
the coatings, the anti-corrosion properties of the samples were evaluated by electrochemical impedance
spectroscopy, potentiodynamic polarization, pull-off, and salt spray tests. The results of the
electrochemical spectroscopy test indicate the improvement of anti-corrosion performance in the
sample containing the inhibitor, so that after 6 hours of immersion in 3.5% sodium chloride solution,
the charge transfer resistance value in the EP sample is 999, and in the ZA@ZIF-8/EP sample is 4082
Ωcm², which confirms the inhibitor effect. Finally, the impact of adding the inhibitor on adhesion and
wettability properties was investigated
