Hydrothermal Synthesis of BaTiO3 Nanotubes on Ti Substrates

Article Preview

A novel, low-temperature two-step synthesis method for producing BaTiO3 thin films patterned in the form of nanotubes on Ti substrates is reported. Firstly, the Ti substrate is anodized to produce a surface layer of amorphous TiO2 nanotube arrays. Secondly, the anodized substrate is subjected to hydrothermal treatment in aqueous Ba(OH)2, where the nanotube arrays serve as templates for their hydrothermal conversion to single-crystal BaTiO3 thin film. This opens the possibility of tailoring the nanotube arrays and their combinations in the hydrothermal bath, to produce ordered, patterned thin film structures of various Ti containing ceramics.
