Preparation of titania nanotube thin films by Langmuir-Blodgett technique

Preparation of thin titania nanotube films has been attempted using Langmuir-Blodgett (LB) technique. The resulting LB monolayer exhibited closely packed arrangement of the nanotube bundles in a monoparticulate layer on the solid substrate. Also, domain structure due to strong lateral interaction among the bundles lying side-by-side was observed even for the LB films deposited at a low surface pressure. Moreover, multilayer deposition of the monoparticulate films provided precise control of the film thickness.
