Annotation Tato diplomová práce hodnotí vliv plniva a molekulové struktury na fotodegradační chování dřevo-plast kompozitů. Jako plnivo byla použita neupravená dřevní moučka z borovice. Kompozity připravené z čistého a nukleovaného polypropylenu s různým plněním dřeva byly podrobeny urychlenému UV stárnutí. Vzorky byly testovány metodami infračervenou spektroskopií, rentgenovou difrakcí, diferenciální skenovací kalorimetrií a mikroskopií. Bylo potvrzeno, že přídavek dřevní moučky a nukleačního činidla do matrice polypropylenu vede ke zvýšení odolnosti materiálu proti fotodegradaci.
Annotation in English This Master?s thesis probes the possible options of influence of filler and molecular structure on photo-degradation of wood plastic composites. In terms of this study, unmodified wood-flour from pine was chosen. Composites prepared from neat and nucleated polypropylenes with various wood filling were exposed to the accelerated UV-radiation. Prepared samples were tested using infrared spectroscopy, X-ray diffraction, differential scanning calorimetry and microscopy. The results showed that presence of wood-flour and beta-nucleator enhances the stability of composites against UV-light.

Research Plan Cílem této práce je zhodnotit vliv plniva a molekulové struktury polypropylenu na fotodegradační chování dřevo-plast kompozitů. Kompozity připravené z čistého a nukleovaného polypropylenu s různým plněním dřeva budou podrobeny urychlenému UV stárnutí a budou testovány metodami dostupnými na UTB, např. FT-IR, WAXS, DSC, mikroskopie.
