Green self-healing coating for zinc corrosion protection

A new study describes the corrosion-resistant coating of polycyclyctic nanocapsules with advantide alkyl pyridine for zinc.
in the course of the study to 3.5 wt. The results of the %NaCl electrolyte solution

. The epoxy resin coating with polycyclic/tyranxane-based benzoic acid/quarterly ammonium-based alkyl pyridine and polyamide/tyrannol/tyrannol sulfonate nanocapsules was compared with the unloaded resin coating.
the coating of the loaded nanocapsules shows improved self-healing corrosion inhibition. Its self-healing properties are characterized by expansion ratio, electrochemical impedance spectrum, tafel polarization, open-circuit potential (OCP), FESEM, and optical microscope imaging. Results over a 50-day interval confirmed stable self-healing behavior, with a corrosion protection rate of 99.87% in scratch coatings containing polycyclicol/dioxin/quarterly ammonium-based alkyl pyridine nanocapsules.
potential synergies
the controlled release of seasonal ammonium alkyl pyridine through fluorescence emission spectroscopy and fluorescence microimaging. The inhibition properties of polycyclic palladium, the formation of Zn (DBS)2 compounds, and the physical adsorption of alkyl alkyl pyridine on metal surfaces are expected to produce potential synergies in corrosion protection and self-healing.
