Abstract

In this paper, a simple process to fabricate free of disorder nanostructures, large area, flat and mechanically robust free-standing TiO2 nanotube (TNT) membranes was developed. Self-organized TNTs with ultrahigh aspect ratio (∼2000) were fabricated via anodization of Ti foil in fluorine containing ethylene glycol. Then by controlling the evaporation rate of rinsing solvent on the as-anodized TNT films in atmosphere, large area TNT membranes were self-detached uniformly from the metallic Ti substrate during the drying process. These free-standing membranes may exhibit many potential applications for optoelectronic devices.
