Abstract
[Abstract] Woodflour/polypropylene composites were prepared with 10 and 20% in weight of woodflour (WF). The influence of the WF, the compatibilizer, and processing aid (WP) in the crystalline structure of the polypropylene was studied by thermal analysis. The results showed that the WF acts as a nucleating agent, increasing the crystallization rate of the PP at the cooling rates studied. The morphological study by SEM proved that the WP increased the dispersion of the filler into the PP matrix, and the ionomer, used like compatibilized improved the adhesion between the PP and the filler obtaining a more uniform morphology. The mechanical properties indicated that the incorporation of the ionomer and the WP enhanced the ductility of the composites at the same time that the materials reached a more uniform morphology. The amount of additives (compatibilizer and WP) included in the woodflour-plastic composite (WPC) formulations was small, for this, the formulations are suitable to use in a possible industrial application.
