SiOx based barrier coatings
Sedláček, Ondřej ; Dzik, Petr (referee) ; Přikryl, Radek (advisor)
The theme of this thesis is based on the preparation and characterization thin films prepared by methods like a Physical Vapor Deposition, Plasma Assisted Vapor Deposition and Plasma Enhanced Chemical Vapor Deposition. The elementary materials for the preparation of these layers are silicon monooxide powder, melamine and hexamethyldisiloxane. These layers have been prepared with regards to their usage like a barrier coatings with emphasis on poisonous organic substances resistance.. We made a characterization of these films. This characterization is consist of researching of their physical properties (the ability to resist permeation of certain organic compounds), and their chemical composition too. We used to some specific method for these characteristics, for example: FTIR, OTR, ellipsometry, SEM and measuring of the permeation of selected industrial pollutants resistance.

Multilayer barrier coatings
Sedláček, Ondřej ; Mazánková, Věra (referee) ; Přikryl, Radek (advisor)
The theme of this work is the preparation and characterization of multilayer barrier coatings to polymer and metal substrates based on SiOx and organic molecules. It deals with the determination of their properties in terms of oxygen permeability and corrosion protection. The starting materials for the preparation of these layers are hexamethyldisiloxane, octafluorocyclobutane and 4,12-dichloro[2.2]paracyclophane. These layers have been prepared with regard to their use as barrier coatings for use in archeology, with the focus on corrosion protection of coated items and other specific requirements museums. For these samples was realized characteristic of both in terms of their physical properties – the ability to resist permeation of oxygen and in terms of their chemical composition. The fourier transformation infrared spectroscopy (FTIR), scanning elektron microscopy (SEM), oxygen transmission rate (OTR), contac angle measurement and corrosion testing were used for the above-mentioned characterisations.
