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 1H NMR, XRD, SEM, and FTIR. Differences between the 1H-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.
