Abstract
Polypropylene / montmorillonite / wood flour nanocomposites are melt-mixed by using a twin screw extruder. The montmorillonite is intercalated by the wood flour and the basal spacing of montmorillonite is increased with increasing the content of wood flour. The exfoliation constantly occurs by adding more than 10 wt.% of maleic anhydride-grafted polypropylene as the compatibilizer, which is used for improving the interfacial adhesion between matrix and filler. Also, the maleic anhydride-grafted polypropylene enhances the mechanical properties of the nanocomposites.
