| Abstract: | SGHDPE/mSiO2 nanocomposities were prepared by melt-blending with treated nano-SiO2 and grafted HDPE. The crystalline behaviour,mechanical properties and thermal property were analysed,the results showed that the crystallinity of SGHDPE/mSiO2 nanocomposites decreased 17% compared with HDPE. The thermal decomposition temperature increased 15 centigrade when nano-SiO2 content was 6%; and the tensile strength increased 25% as the content of nano-SiO2 was 10%. |
