| 摘 要： | 通过熔融共混法制备了聚丙烯 纳米SiO2 复合材料。利用扫描电镜(SEM)观察了纳米SiO2 在聚丙烯中的分散效果,结果表明纳米SiO2 团聚少,分散好。测试结果表明,当使用 2份纳米SiO2 时,聚丙烯 纳米SiO2 复合材料的力学性能最优:与纯PP相比,V形缺口冲击强度提高了 90 %,弯曲强度提高了 2 3%,拉伸强度提高了 5 %;最后,设想一种新的模型来解释聚丙烯 纳米SiO2 复合材料可能的微观界面结构

| Abstract: | The PP/nano-SiO 2 composite was prepared by means of melting blending. SEM graph showed that nano-SiO 2 was little aggregated and well dispersed in PP. Testing result showed that the mechanical performance of PP/nano-SiO 2 composite was optimal when PP/nano-SiO 2 composite contained nano-SiO 2 2wt%. Compared with unmixed PP, the Izod impact strength, the bending strength, and the tensile strength were increased by 90%, 23%, 5% respectively. In the end, Author supposed a new interfacial model to explain the microstructure of PP/nano-SiO 2 composite. |
