In this work, epoxy/2pack coatings containing
polyaniline (PANI) in combination with Ag and
ZnO nanoparticles have been synthesized. The
nanoparticles were incorporated with bisphenol-A
diglycidyl ether epoxy resin and polyamino-amide.
The mechanical properties of the fabricated coatings,
such as the pendulum hardness, scratch resistance, and
impact strength, were studied. The composition of the
fabricated coatings was confirmed by attenuated total
reflectance infrared spectroscopy measurements. The
thermal degradation and indentations were characterized
through the use of differential scanning calorimetry
and nano-indentation techniques, respectively. The
surface morphology of the fabricated coatings was
characterized using field-emission scanning electron
microscopy. The synergistic effects of the Ag and ZnO
nanoparticles on the corrosion resistance of the coatings
after different exposure periods in 3.5% NaCl
solutions were determined by electrochemical impedance
spectroscopy. All the results were consistent
with one another and confirmed that the addition of
Ag and ZnO nanoparticles improved the mechanical
properties of the coatings. This effect also led to a
notable increase in the corrosion resistance of the
PANI coatings.
