摘　　要：采用熔融共混法制备了聚氯乙烯/纳米二氧化硅(PVC/nano-SiO2)复合材料,研究了nano-SiO2用量对复合材料力学性能的影响,并利用扫描电镜(SEM)分析了nano-SiO2在PVC基体中的分散性。结果表明:随着nano-SiO2用量的增加,PVC/nano-SiO2复合材料的冲击强度和拉伸强度均呈先增后降趋势,而弯曲模量则呈增加趋势;另外,随着nano-SiO2用量的增加,其在PVC基体中的分散性逐渐变差。Polyvinyl chloridelnano-sitica（PVC/nano-SiO2） composite was prepared by melt blending method. The effects of nano-SiO2 content on mechanical properties of the PVC/nano-SiO2 composite were studied, and the dispersion of nano-SiO2 in PVC matrix was analyzed by scanning electron microscope（SEM）. The results show that the impact strength and tensile strength of the PVCInano-SiO2 composite both increase at first and decrease later with the increase of nano-SiO2 content, but the flexural modulus of the PVC/nano-SiO2 composite evidently increases with the nano-SiO2 content. Moreover, the disparsion of the nano-SiO2 in PVC matrix becomes worse gradually with the increase of nano-SiO2 content.
