| 摘 要： | The dynamic mechanical properties of wood powder/polypropylene composites with different wood content treated and untreated with the compatibilizer have been studied. It has been found that addition of wood powders and the compatibilizer can both improve the viscoelasticity of composites. Glass transition temperature (Tg) of appropriate wood powder-filled composites decreased. The value for the storage modulus (G') increased gradually with increasing wood powder content. The addition of the compatibilizer made glass transition temperature shift to a higher temperature. DSC (Differential Scanning Calorimetry) results showed that, for pure PP, the addition of the compatibilizer decreased its melting point, and increased its Calorie of Melt at the same time. For the composite with 50 % wood powder treated with the compatibilizer, the melting point was almost unchanged, but its Calorie of Melt decreased.
