Te efect of surface modifcation with selected alkoxysilanes on the photocatalytic properties of TiO2 used in the reaction of formaldehyde photodegradation to UV radiation was investigated. Titanium dioxide - TytanpolŽ A-11, a pigment of anatase structure of the untreated surface, was used. Silane coupling agents were hydrolysed and then deposited directly on the surface of the TiO2. Te alkoxysilanes - 3-ethacryloxypropyltrimethoxysilane, vinyltrimethoxysilane or N-2-(aminoethyl)-3-aminopropyltrimethoxysilane were applied in the amounts of 0.5, 1 or 3 wt. parts per 100 wt. parts of TiO2. Te unmodifed and modifed titanium dioxide were used for the dip-coating of textile fabrics, and their photocatalytic properties were tested using UV radiation with TiO2 as a photocatalyst. Te results proved the very good photooxidative activity of TiO2 introduced into the structure of polyester fabric.
