Novel thin films of titanium dioxide dispersed in a polymeric matrix have been prepared by a chemically modified sol-gel technique. Nanostructured films of pure TiO2 in the anatase form are obtained after annealing at 500 degrees C. SEM, TEM and TG/DTA are used for the structure characterisation of TiO2 films. The role of the polymer in controlling the microstructure is confirmed. The first application of this technique in gas sensor field is presented in this work. Ethanol and methanol sensing properties are tested and reported. TiO2 sensors can detect very well concentration required for breath analysers. (C) 2000 Elsevier Science S.A. All rights reserved.
