 Full text | Abstract: The effect of surface modification with selected alkoxysilanes on the photocatalytic properties of TiO2 used in the reaction of formaldehyde photodegradation to UV radiation was investigated. Titanium dioxide - Tytanpol® 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. The alkoxysilanes - 3-methacryloxypropyltrimethoxysilane, 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. The unmodified and modified 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. The results proved the very good photooxidative activity of TiO2 introduced into the structure of polyester fabric. |
