- Title
Synthesis and characterization of supramolecular corrosion inhibitor nanocontainers for anticorrosion hybrid nanocomposite coatings.

- Abstract
Supramolecular nanocontainers were prepared by forming an inclusion complex (IC) between β-cyclodextrin (β-CD) and a corrosion inhibitor-either 2-mercaptobenzothiazole (MBT) or 2-mercaptobenzimidazole (MBI)-at room temperature or under sonication. These nanocontainers were used to create an anticorrosion coating that releases corrosion inhibitor only upon the initiation of corrosion. The supramolecular nanocontainers were characterized by H NMR, XRD, SEM, and FTIR. Differences between the H-NMR, FTIR, and XRD spectra of the physical mixtures and the inclusion complex demonstrated the formation of MBT/β-CD and MBI/β-CD supramolecular nanocontainers in the solid phase. Crystals of the β-CD/MBT and β-CD/MBI inclusion complexes adopted head-to-head channel-type and cage-type conformations, respectively.
