Abstract

Titania nanotube arrays were formed by electrochemical anodic etching of titanium from glycerol solutions with addition of 0.5% HF and analyzed by scanning probe microscopy and ellipsometric analyzes. Potentiostatic curves allow identifying several different stages of growth of nanotubes of titanium dioxide, however, this method does not establish specific parameters of the surface. We demonstrated that analysis of the spectrum ellipsometric parameters Psi and Delta can used as a criterion of quality, frequency, depth and other characteristics of the obtained arrays of titania nanotube. The use of these methods of analysis allowed to fully characterize the different stages of growth of titania nanotube from glycerol solutions and can be used for quality control the resulting structures for various applications.
