Kinetic properties of layer-by-layer assembled cerium zinc molybdate nanocontainers during corrosion inhibition

• We investigate the responsive release of imidazole from CZM nanocontainers.
• Acoustic cavitation leads to the formation of smaller CZM nanoparticle.
• We study kinetic models for imidazole release from CZM nanocontainers.
• Improved anticorrosion performance by incorporating CZM nanocontainers in coatings.

In the present study the loading of imidazole in between polyelectrolyte layers was carried out and the responsive release of imidazole was studied. Cerium zinc molybdate (CZM) was used as a core corrosion inhibitive nano pigment. The release rate of imidazole from CZM nanocontainer has been quantitatively estimated in water at different pH. The validation of quantitative analysis of release of corrosion inhibitor was carried out using the kinetic models. Results of electrochemical corrosion analysis of nanocontainer coatings on mild steel (MS) panel showed significant improvement in the anticorrosion performance of the nanocontainer/alkyd resin coatings.
