INTRODUCTION
Interest in the use of woodflour as a filler in thermoplastics has increased because of the many advantages offered, including low density, high strength and stiffness of the final product, and the low cost of woodflour (an industrial waste product) (1-3). Furthermore, woodflour does not cause abrasion in the extruder screws during processing of the composite and had less ecological impact than mineral fillers (4). Despite the aforementioned advantages, it is difficult to achieve strong interfacial adhesion between the hydrophilic surface of the wood and the hydrophobic thermoplastic polymers because the surface free energy of both components is ...
