Hybrid n-Alkylamine Intercalated Layered Titanates for Solid Lubrication.

The intercalation of different primary n-alkylamines in the structure of a layered titanate of the lepidocrocite type (HTiO) for application in high-temperature solid lubrication is reported. The intercalation process of the amines was explored by means of in situ small-angle X-ray scattering (SAXS), with variations in alkyl chain length (3-12 carbon atoms) and the amine/titanate ratio. The intercalation process was found to be completed within 5 min after mixing of the precursors in water at 80 °C.
