Sol-gel process using reverse micelles
 Lukešová, Magdalena ; Čeppan, Michal (oponent) ; Veselý, Michal (vedoucí práce)
This study describes preparation of transparent thin films of titanium dioxide by sol-gel process with reverse micelles, which represent a unique system for production of uniform particles. A non-ionic surfactant was used as a templating agent. Material printing as a specialized inkjet printing technique was used to prepare titania thin films of 1–4 layers. After calcination the prepared films of titanium dioxide were characterised by band gap energy. The structure of the films was described by optical microscopy and SEM. Photocatalytic activity was verified by oxidation reaction of 2,6-dichloroinfophenol and by degradation of stearic acid directly printed on the active layers. Photo-induced hydrophilicity was characterised by contact angle measurement of water wettability. Photocatalytic efficiency of prepared films increased with increasing number of titania layers.
