The thesis will be focused on preparation and characterization of novel fully biodegradable polymeric systems based on thermoplastic starch (TPS). With respect to the TPS content, modified TPS will be added to the biodegradable polymer matrix as a filler as well as it will be used as a continuous phase. The project will be aimed at various types of native starch modification such as esterification, grafting and plastification in order to improve the sustainability of the physical and mechanical properties of the resulting materials. Modified starch will be used for preparation of TPS by addition of various plasticizers with the main goal of optimizing the TPS composition and processing conditions for achieving required mechanical properties such as higher strength and humidity resistance. Prepared materials will be investigated by determination of structural parameters and selected physical properties allowing understanding of relations between composition, structure and properties of multiphase materials.
