Dependence of Binder and Photocatalyst in Photocatalytically Active Printing Ink

Popis výsledku v původním jazyce

Photocatalytically active printing ink changes its colour when exposed to UV light. The ink is based on photocatalyst which decomposes organic dye in presence of UV light causing the changes in colour. Such process can be used as a simple UV dosimeter asits colour change depends on duration to UV light exposure. We have prepared such an ink based on redox dye 2,6-dichloroindophenol (DCIP), photocatalyst titanium dioxide (nanodimensional anatase), reducing agent (glycerol) and two different water basedbinders ? hydroxyethylcellulose (HEC) and polyvinyl alcohol (PVA). Prepared ink was applied onto a substrate, exposed to UV light and analysed by UV/Visible spectra. When the ink was exposed to UV light, the colour of the redox dye DCIP was changing fromblue to colourless that belongs to the dihydro DCIP form. The colour change depends on several factors: on the amount of TiO2 and UV exposure, as well as on the type of binder. In this work the influence of two selected binders and the a
