Material printing of ozone dosimeters
Petříčková, Zuzana ; Čeppan,, Michal (referee) ; Veselý, Michal (advisor)
This study presents various methods of measuring ozone and consolidates current state of knowledge in the field of disposable printed ozone dosimeters. The paper also identifies prospective dyes for preparation of ozone dosimeters available on the market. Information gathered from literature review was used to prepare dosimeters based on two different dyes. These were calibrated for screen printing technology and their sensitivity to ozone was optimized to achieve visual detectability. Prepared samples were observed and studied while being exposed to ozone. Then, long term mechanical and chemical properties of these were tested in order to identify appropriate conditions for storage.

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.
