Abstract

Fabrication of TiO₂ and Nb-containing TiO₂ nanotubes on alumina and flexible polymeric substrates Kapton HN has been performed by means of electrochemical anodization method. To investigate the morphology of the structures and the roughness of the substrates, scanning electron microscopy and atomic force microscopy have been utilized. The preparation of well-ordered titania structures with the higher concentration of Nb was possible when in the electrolyte the ethylene glycol has been substituted by more viscous glycerol. Sensing properties of obtained tubular arrays have been tested towards nitrogen dioxide.
