摘要:The Theological behaviour, dispersion, crystallization behavior, mechanical properties, fracture surface morphology of polyethylene (PE)/TiO<inf>2</inf> nanocomposites prepared by melt compounding were investigated using rheometer, energy dispersive X-ray spectrometer (EDX), polarized microscopy, impact tester, universal testing machine and field-emission scanning electron microscopy (FE-SEM). The Theological analysis indicated a fine dispersion of TiO <inf>2</inf> during the melt compounding. The large scaled surface dispersion of TiO<inf>2</inf> nanoparticles was revealed by the EDX composition distribution maps. The introduction of 2.0 wt% TiO<inf>2</inf> in composites improved the mechanical properties significantly compared to neat PE, and resulted in 45% increase in notched impact strength. Moreover, the further analysis and discussion showed the mechanical properties of the composites were controlled by the dispersion conditions of TiO<inf>2</inf> and its nucleating effect on PE crystallization. © VSP 2006.
