Aplikace nových materiálů pro tvorbu nábytku budoucnosti s ohledem na uživatelský komfort =: Aplication of new materials for furniture development with respect to user comfort /

This thesis was focused on solid wood surface treatments. The goal of the thesis was to achieve superhydrophobic behavior of solid wood surface and its application on furniture design – bathroom furniture. In the first part of experiment the thesis dealt with plasma discharge surface treatment of 3 different wood species – larch (Larix decidua), oak (Quercus robur) and pine (Pinus sylvestris). These treatments were performed in atmospheric and inert (nitrogen) environment with different time of treatment. Effect of plasma discharge was evaluated by contact angle measurement. The second part of the experiment was focused on wax deposition on wooden samples with different roughness. The wax n-hexatriacontane is naturally found as a component of wax blends on the surface of plant leaves. The deposition was performed by physical evaporation in vacuum. This wax has a self-assembly ability, e.g. it creates 3D objects on the surfaces after deposition. The dependence of roughness on self-assembly and wettability in time were examined. Self-assembly ability was observed with scanning electron microscopy and confocal microscopy. Plasmatic treatment hasn´t led to increased hydrophobicity, nevertheless, a significant increase of hydrophilicity was observed during contact angle measurement which could be used as a preparation for surface coating. Surface treatment with wax has led to significant increase of hydrophobicity. Samples of larch and oak achieved superhydrophobic surface behavior (CA > 150°) and pine samples achieved highly hydrophobic behavior (CA > 140°).
