This diploma thesis deals with the synthesis of an organosilica polymer which could be used as a binder for titanium dioxide photocatalytic layers. The main reason for incorporating the binder into the photocatalytic layers is not only the improving of the mechanical properties, but above all, the binder could help with production of low-temperature photocatalytic layers, that could be applied to heat-sensitive materials such as plastic materials. This could create layers on flexible materials that could be easily made into any shape. The work focuses on the synthesis of organosilica polymer from the organosilica precursor and subsequent characterization of the binder. Surface tension, viscosity, density, XRD, thermal analysis of silica binder solutions was performed. Titanium dioxide compositions with this binder were prepared, then they were printed and the layers were treated with UV and plasma. Treated layers were examined by FT-IR and a voltamperometric characterization was performed.
