Nanocomposite varnishes
Hlavčo, Tomáš ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This work deals with issues of nanoparts and nanotechnology and it’s applications in the sphere of dielectrics. Primary objective has been to make series of varnish samples filled with nanoparts. Then we have measured dependencies of absorber and resorber currents and we have been monitoring changes of dielectric properties against unfulfilled samples. Used materials were epoxy resin TSA 220S filled with nanoparts of silicon oxide.

Development of polymer repairing material
Juřička, Viktor ; Seidlová, Michaela (referee) ; Drochytka, Rostislav (advisor)
Rehabilitation of concrete constructions is important and constantly evolving industry, where development of new, advanced materials contribute to increasing the quailty and effectivness of the remedation process. This work is focused on the development of repairing polymeric material that is able to withstand the conditions of the energy industry and other industrial operations, while effectively utilizing recycled materials. The thesis contains a detailed overview of legislative tests of individual properties and is proposing recipes of appropriate repairing polymeric materials, including a proposal for its application and the pretreatment of input materials.

Monitoring properties of nanocomposites on base epoxy
Libra, Miroslav ; Rozsívalová, Zdenka (referee) ; Polsterová, Helena (advisor)
The present thesis deals with the study of nanotechnology in the field of composite materials (nanocomposites). Furthermore, the production, composition and electrical properties of these materials. Samples for the experiment are made of epoxy resin as matrix and titanium dioxide TiO2 as fillers with different benefits. Are the measurements the temperature dependence of permittivity, loss factor and internal resistivity.
