Sažetak
The aim of this work was to prepare poly(3-hydroxybutyrate)/montmorillonite (PHB/MMT) composites on the laboratory press with heating, and to determine the influence of different food simulants on the composites and the filler migration. Analysis of the food simulants after migration testing was conducted with UV/Vis spectroscopy. Due to the established hydrolysis of PHB under the influence of the food simulants, it was impossible to determine the migration of MMT from PHB/MMT composites. Differential scanning calorimetry (DSC) confirmed the degradation of PHB. This research showed the potential of UV/Vis spectroscopy in dealing with the influence of food simulants on polymer composites.
