| Summary: | 碩士 === 東海大學 === 化學工程學系 === 89 === Abstract
The mechanical properties of the polyethylene/wood flour (HDPE/WF) composite systems are not satisfactory due to the week interaction between the wood flour and HDPE matrix. Several compatibilizers are added into the composites to enhance the interfacial interactions. Dynamical mechanical thermal analysis (DMTA) and rheological properties were used to investigate the interaction of the interface between the wood flour and HDPE matrix. The composite viscosity was found to be increased with wood flour loadings. Various compatibilizers were made to improve the wood flour-matrix interfacial adhesion. Compatibilizers increased the viscosity of the composites due to high interfacial interaction. The increasing of compabilizers contain in the composites will also increase the viscosity. The drop in the amplitude and the shift in the damping peak(tanδ) indicates the strong interaction between the wood flour and the HDPE matrix. On the other hand, the increase in the storage modulus (E’) demonstrates the improvement of mechanical properties.
