Titanate matrices as potential corrosion inhibitor nanocontainers

Layered titanates as inhibitor nanocontainers were studied in this paper. Pyridine as a typical inhibitor was introduced into the titanate matrices and its extraction from the matrices was studied. The results show that the increase of pH of media favors the extraction of pyridine from the matrices. The layered structure of titanate containers remains stable after both introduction and extraction of pyridine. Additionally, corrosion inhibition measurements also confirm the effective release of pyridine from the titanate nanocontainers.
