  • Method for preparing transparent free-standing titanium dioxide nanotube array film
    Patent number: 10882754
    Abstract: The present invention provides a method for preparing a transparent free-standing titanium dioxide nanotube array film. In the method, with the titanium foil as a substrate, the titanium dioxide nanotube array film is obtained by anode oxidation on the surface of the titanium foil. Upon high temperature annealing, the titanium dioxide nanotube array film naturally falls off to obtain the transparent free-standing titanium dioxide nanotube array film. The method according to the present invention features simple operations, saves time and cost. With the method, a completely strippable titanium dioxide nanotube array film may be prepared, and in addition, morphology of the titanium dioxide nanotube is not damaged. The free-standing and complete titanium dioxide nanotube array film facilitates transfer and post-treatment, has the feature of transparency and may be in favor of the applications to the studies such as photocatalysis and the like.
