Modified Polypropylene Filled with Nano-Al2O3
The mechanical properties of polypropylene (PP) could be strengthened after PP was filled with nano- Al2O3. Tests of mechanical properties and analyses of scanning electron microscope (SEM), transmission electron microscope (TEM) and wide-angle X-ray diffraction (WAXD) showed that the crystallinity of PP/nano- Al2O3 (3wt%) was improved 9.5% compared with PP’s, the tensile strength was enhanced 10.7 % and the notched impact strength was intensified 21%, the comprehensive property of nano-composites was by far the best .
