摘　　要：研究了纳米二氧化硅(SiO_2)对聚苯硫醚(PPS)力学性能的影响。通过透射电子显微镜分析,经硅烷偶联剂处理的纳米SiO_2粒子在PPS基体中的分散达到了纳米水平。添加少量的经表面处理及超声波振荡的纳米SiO_2后,PPS的部分力学性能尤其是冲击性能有明显提高。The influence of the nano-SiO2 content on the mechanical property of the modified PPS is researched. The results showed that the mechanical property, especially the impact strength, could be obviously improved by nano-SiO2. At the same time, the disperson of nano-SiO2 particles treated with the silane coupling agent and the ultrasonic wave oscillation in the PPS matrix reached the nanoscale by TEM analysis.
