The effects of maleated polybutadiene-grafted polypropylene (MAPB-g-PP) content on the properties of wood flour/polypropylene composites

摘要

This research investigated the effects of a compatibilizer of maleated polybutadiene-grafted polypropylene (MAPB-g-PP) on the properties of wood-flour/polypropylene composites through the analysis of mechanical properties, water absorption, thermogravimetry, differential scanning calorimetry, and scanning electronic microscopy. The results demonstrate that the mechanical properties of composites were significantly increased; the thermal stability and water absorption were improved. The crystallization temperature and crystallinity were decreased. These improvements have been attributed to the strong interfacial interaction of MAPB-g-PP with both wood and polypropylene. J.
