Annotation Tato práce zkoumá vliv vláknité celulózy esterifikované třemi karboxylovými kyselinami na její disperzi v kompozitu a vliv plniva na vlastnosti tohoto kompozitu. Byla zkoumána tepelná stabilita modifikované celulózy a její vliv na barevnost kompozitu, jeho tepelné chování a mechanické vlastnosti.
Annotation in English This Bachelor´s thesis studies influence of fibrous cellulose esterification by three carboxylic acids on its dispersion in composite and an effect of the filler on the composite properties. Thermal stability of cellulose was examined as well as its effect on color, thermal behaviour and mechanical properties of prepared composite.
Keywords celulóza, karboxylová kyselina, esterifikace, disperze, mecha?nické vlastnosti, barevnost

Research Plan - Stručně popište chemickou i nadmolekulární strukturu celulózy, uveďte zdroje celulózy.
- Popište princip esterifikace, proces úpravy celulózy a přípravu kompozitu
- Popište použité analytické metody
V praktické části:
- Zhodnoťte tepelnou stabilitu upraveného plniva
- Připravte kompozit s iPP resp. HDPE matricí
- Zhodnoťte tepelné chování kompozitu pomocí DSC
- Zhodnoťte vzhledové (barevné) rozdíly pomocí kolorimetrie
- Zhodnoťte mikroskopickou strukturu
- Porovnejte tahové charakteristiky připravených kompozitů
