This thesis deals with the determination and evaluation of antibacterial properties of coatings and surface finishing. The thesis verified antibacterial, physico-mechanical and chemical properties of water-based coatings themselves with added antibacterial particles. For better orientation in issue of this thesis are generally described coatings, antibacterial substances and tested bacteria. The aim is to determine the effect on the properties of coatings with added antibacterial substances. How effective is the resistance of the tested coatings with added ingredients to the action of bacteria and fungi as well as to assess whether they are suitable for use in surface finishing furniture parts and whether they have the expected properties.

The diploma thesis deals with preparation of acrylic copolymers via emulsion polymerization technique. Two sets of copolymer samples were prepared within this thesis, n BA/MMA and 2-EHA/MMA copolymers. n-BA/MMA copolymer sample was used for investigation of effect of surfactant concentration as well as effect of addition of acrylic acid to the feed composition. During all the copolymerizations, conversion was observed via solids content evaluation as the reaction progressed. Copolymerization was lead under inert atmosphere at continuous stirring and 80 °C for 4 hours. Glass transition temperature of samples was determined with DSC and Vicat softening point was measured as well. Data acquired from measurements were compared with values calculated with Fox equation which was used for modelling molar ratio of monomers in initial feed.
