Oriented growth of thin films of titanium oxyfluoride at the interface of an air/water monolayer
Abstract
When a monolayer of dioctadecyldimethylammonium bromide is formed on the surface of mixed aqueous solutions of (NH4)2TiF6 and H3BO3 with a B/Ti molar ratio below 1.5, oriented crystallites of NH4TiOF3 are produced and grown at the hydrophilic interface of the monolayer to yield a self-supporting thin film within a few days.
