Evaluation of the Photocatalytic Properties of Textile Fabrics Modifed with Titanium Dioxide of Anatase Structute

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.
