"Paper deals with the preparation of layers consisting of TiO2, polydimethylsiloxane (PDMS)/TiO2 and PDMS/TiO2/SiO2 using sol-gel method and comparison of their selected properties, namely photoactivity and chemical stability. SiO2 was added due to the increase of chemical stability. Thickness of prepared layers was in the range 100 nm (layers consisting of pure TiO2) to 1 ?m (layers PDMS/TiO2/SiO2). The essential emphasis was given to the determination of photoactivity towards degradation of model dye methyl blue in aqueous solution and chemical stability in water at 85 \u00B0C). Prepared layers containing only anatase did not show any photoactivity. It was observed after addition of polydimethylsiloxane ( PDMS). It was found that rate of photodegradion is dependent on the annealing temperature and amount of titanium precusor in the starting mixture."@en .
