Abstract

Wood flour (WF) based natural polymer biocomposites were produced using the equal channel angular pressing (ECAP) technique. The wood particle structures were disrupted and the cellulose crystallinity was decreased while bulk materials were formed with continuous phase structures by the severe shear-deformation during ECAP. The mechanical properties of the processed WF materials were enhanced when the processing temperature was increased due to enhanced intermolecular interactions and thermal crosslinking reactions among WF components. The processing capability was improved by using wheat gluten (WG) as additives, leading to significantly reduced processing temperature. Effective chain penet..
