Abstract
Cílem bakalářské práce je zjistit využitelnost celulózových nanokrystalů s hydrophobicí ligninovou povrchovou úpravou jako potenciální zelené výztuže při zpracování nano-bio-kompozitů na bázi PLA matrice. Nanokrystaly celulózy povrchově modifikované ligninem (L-CNC) byly plněny v rozmezí 1 až 3 hm. %. Měřeny byly fyzikální, mechanické a termické vlastnosti. Morfologie a disperze L-CNC v matrici byla zkoumána pomocí rastrovacího elektronového mikroskopu (SEM).
The aim of the bachelor thesis was to find out the applicability of cellulose nanocrystals with hydrophobic lignin coating as a potential green reinforcement in the processing of nano-bio-composites based on PLA matrix. Cellulose nanocrystals with lignin surface coating (L-CNC) were filled in the range of 1 to 3 wt. %. Physical, mechanical and thermal properties were measured. L-CNC morphology and dispersion in the PLA matrix was examined by scanning electron microscope (SEM).
