Plasmochemical treatment of substrates and coatings in R2R arrangement
Patakyová, Sylvia ; Homola,, Tomáš (referee) ; Dzik, Petr (advisor)
This bachelor thesis deals with the comparison of the properties of two titanium dioxide types, which is due to its semiconductive properties commercially used in photoactive layers. The main reason for comparing these sources is their different price which can have possible impact on industrial use. Photoactive layers formed by various wet deposition techniques are cured by atmospheric plasma. The effect of plasma on individual depositions is investigated by electroanalytical methods. Voltametric and chronoamperometric characteristics indicate the dependence of the substrate activity on the time or distance of plasma treatment. Surface of composites were scanned by SEM and the mutual surface properties of untreated composites and the effect of siloxane binder on them were analyzed.

Plasmochemical treatment of photoanodes with semiconducting oxide layer
Ďurašová, Zuzana ; Zita, Jiří (referee) ; Dzik, Petr (advisor)
This diploma thesis deals with a plasmochemical treatment of photoanodes with an active layer containing TiO2 deposited on two different substrates by material printing. The plasmochemical treatment was performed by a low-temperature ambient-air plasma using a diffuse coplanar surface barrier discharge (DCSBD). The experimental part is focused on the investigation of DCSBD influence on the fabricated photoanodes photoelectrochemical properties, and the influence of plasma treatment time. Process optimization was achieved by height adjustment of the electrode. The processed coatings were electrochemically investigated by linear sweep voltammetry and chronoamperometry.
