Abstract: 

This study describes the elaboration and characterization of plasticized starch composites based on lignocellulosic fibres. The transformation of native to plasticized starch and the preparation of TPS blends were done with a new lab-scale mixer based on an original concept. Firstly, the impact of process parameters (temperature, speed screw) on the quality and the structural properties of plasticized starch were examined by MEB and DRX. After that, we focused on the elaboration of various formulations based on plasticized starch matrix by varying TPS formulation, filler content and fibres length. The morphological and rheological properties of TPS/flax blends have been analyzed by TGA, MEB and DMTA. © Lavoisier 2016.
