Preparation and Properties of Thermoplastic Polyurethane Composites Filled with Powdered Buckwheat Husks.Bio-based fillers for the polymer composites are still interesting from the scientific and industrial point of view, due to their low cost and renewable nature.  In this work partially green composites were obtained by the mixing of thermoplastic poly(ester-urethane) with the unmodified and modified (by acetylation) grinded buckwheat husks.  Obtained biocomposites were characterized in the terms of their chemical structure (FTIR), microstructure (SEM), thermal stability (TGA), thermomechanical properties (DMTA), and selected mechanical properties.  Obtained results confirmed the possibility of using powdered buckwheat husks as filler for thermoplastic polyurethane.
