英文摘要: Abstract(#br)In this study, for the first time, the corrosion mitigation ability of zinc intercalated kaolin (K) as an inorganic and cost-effective nanocontainer was studied. The impact of kaolin modification by zinc ions on the epoxy ester coating corrosion protection ability was surveyed by EIS (Electrochemical impedance spectroscopy) and salt spray tests. XRD (X-Ray diffraction) results showed that feeding the kaolin particles by zinc ions increased the interlayer space of the galleries. The R ct (charge transfer resistance) values obtained from the EIS analysis of the scratched coating were found to be around 9800, 34693, and 52188 Ω cm 2 for neat, K, and KZn (modified K particles with Zn ions) epoxy coated samples after 6 h from immersion. The physical and thermal-mechanical...
