Abstract

Abstract: Modified SiO2 nanoparticles were filled into polycarbonate (PC) by two different methods. In order to enable the inorganic nanoparticles dispersed evenly in the PC matrix, the silane coupling agent KH-550 was used to modify the surface of SiO2 nanoparticles by wet treatment. The relationships between mechanical and processing properties of PC/SiO2 composite and silica content were examined, and product performance characterized. The characteristics of rigid modified inorganic nanoparticles filled on a typical engineering plastic PC were also studied to explore the mechanism of its strength enhancement and the rheological properties of PC/SiO2 composite. The results show that the modified SiO2 spheres had uniform dispersion in PC matrix and PC/SiO2 composite had good tensile strength and rheological effect.

Key words: SiO2, polycarbonate, surface modification, mechanical performance, rheological property

摘要： 采用SiO2纳米粒子填充改性聚碳酸酯(PC)，为使无机纳米粒子在基体PC中分散均匀，经硅烷偶联剂KH-550对SiO2纳米粒子进行表面处理，分析了改性SiO2纳米粒子对复合材料机械与加工性能的影响，并对复合材料进行了分析表征，探讨了无机刚性纳米粒子填充改性典型工程塑料PC的特点并探索其增强增韧的机理，研究了复合物的粘流变性能. 结果表明，改性SiO2纳米粒为球形，在PC基体中分散均匀，湿法改性制备的PC/SiO2纳米粒子复合材料的力学拉伸性能和流变性能最好.
