Originální abstrakt

This work is focused on an approach to improve the impact toughness of poly (lactic acid) (PLA) without compromising the bio-based carbon content and compostability of PLA. According to the literature, low-crystalinity and morphous polyhydroxyalkanoates (PHA) copolymers were demonstrated to be very effective in improving the toughness of PLA at modest loading levels of 10-20 weight percent. The present study includes preparation and characterization of PLA/PHA blends with two different amorphous PHA copolymers. Another strategy for improvement of the impact performance of the prepared PLA/PHA blends was applying an annealing procedure after ijection modling Crystalline morphology and crystal modification before and after the annealing process of all prepared PLA/PHA blends as well as for the virgin PLA were studied by X-ray diffraction measurements. In the present study, an outstanding impact performance was achieved in the case of PLA/PHA2 blends.
