Nanocontainers Boost Corrosion Protection

nanocontainers loaded with corrosion inhibitors

Dispersions of nanocontainers loaded with corrosion inhibitors can boost corrosion protection, whether applied to bare metallic substrates or incorporated into coatings, researchers have found.

“Enhanced Corrosion Protection via Combination of Inhibitor-Loaded Nanocontainers,” recently published in ACS Applied Materials & Interfaces, reports on the synthesis of layered double hydroxides (LDHs) nanocontainers loaded with different corrosion inhibitors (vanadate, phosphate, and 2-mercaptobenzothiazolate) and the characterization of the resulting pigments by X-ray diffraction (XRD) and transmission electron microscopy (TEM).

The anticorrosion activity of these nanocontainers with respect to aluminum alloy AA2024 was investigated by electrochemical impedance spectroscopy (EIS).

The bare metallic substrates were immersed in dispersions of nanocontainers in sodium chloride solution and tested to understand the inhibition mechanisms and efficiency. The nanocontainers were also incorporated into commercial coatings used for aeronautical applications to study the active corrosion protection properties in systems of industrial relevance.

“The results show that an enhancement of the active protection effect can be reached when nanocontainers loaded with different inhibitors are combined in the same protective coating system,” reports the team of German and Portuguese scientists.

The full report (ACS Appl. Mater. Interfaces, 2010, 2 (5), pp. 1528–1535) is available here.
