Titania nanotube arrays fabricated by anodization method may de-attach from the parent Ti metal foil. How can we increase the adhesion strength of the nanotube to the parent Ti metal foil to keep them fixed?
you can use the immersion of Titania nanotubes in aprotic solvents with lower polarity, such as petroleum ether, as a post-treatment way to increase the adhesive force. For more details, see the following: https://www.nature.com/articles/srep07178
