Printing inks optimization for ozone dosimeter
Petříčková, Zuzana ; Krystyník,, Pavel (referee) ; Veselý, Michal (advisor)
In the study various methods to measure concentration of ozone were investigated. Emphasis was placed on opto-chemical sensors, which change their colour when exposed to augmented dose of the substance. Numerous solutions have been prepared by changing ratios of substances and were used to make ozone dosimeter. The goal was to produce highly sensitive composition which would change colour noticeably when exposed to ozone, with good mechanical properties when dried up. When the solution with required properties had been discovered, it is suitably for silk-screen printing was tested.

Printed ozone dosimeter
Védlová, Petra ; Čeppan, Michal (referee) ; Veselý, Michal (advisor)
This diploma thesis deals with ozone measurement methods, especially focusing on opto-chemical methods, when the color change of the sample is examined. Moreover it deals with dyes that are sensitive to ozone and their degradation kinetics. In the experimental part kinetics of dyes Orange I, Orange II and Indigo carmine is examined, These dyes are prepared in the form of ink of different composition. These inks are applied to diverse substrate materials by the material printing method, further by using a Baker film aplicator and in the end by the screen printing method. The properties of the samples are evaluated as well as factors affecting their degradation.
