硅烷接枝HDPE/纳米SiO2复合材料的制备与性能
Preparation and Properties of SGHDPE/mSiO2 Nanocomposites
【摘要】 将经表面处理后的纳米SiO2和硅烷接枝高密度聚乙烯(HDPE)熔融共混制得硅烷接枝HDPE/纳米SiO2复合材料,并对其结晶行为、力学性能及热性能进行了研究。结果表明:与HDPE相比,硅烷接枝HDPE/纳米SiO2复合材料的结晶度降低约17%;在纳米粒子含量为6%时,热分解温度提高了15℃;在纳米粒子含量为10%时,体系的拉伸强度提高了25%。
【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%.
