Surface Texturing of Porous TiO2 Film by Mist Deposition of TiO2 Nanoparticles

Watanabe et al. have easily fabricated unique and various microstructures of titanium oxide (TiO2) film including macro porous structure, chromatic veins and rings by mist deposition method on silicon substrate with mild preparation conditions. Rutile phase TiO2 nanoparticles are directly used as starting materials to prepare film, which is a simple preparation process. It is found that several different microstructures exist in the sample and change with the varied positions from the center to the edge of the film with the concentration of the TiO2 suspension of 0.06 mol L-1, the deposition time of 30 min, and the flow rate of 1 L/min. The surface texturing shows apparent distinction as the concentration of the TiO2 suspension decreased to 0.03 and 0.01 mol L-1.
