| 摘 要： | 采用正硅酸乙酯（TEOS）水解生成的SiO2对纳米ZnO进行表面包覆，制备了ZnO—SiO2纳米复合粒子，并用该复合粒子对聚碳酸酯（PC）进行改性处理。考察了纳米ZnO的表面包覆改性效果，研究了不同纳米复合粒子用量时复合材料的耐光氧老化性能，并探讨了纳米复合粒子对复合材料注塑工艺的影响。结果表明，SiO2成功包覆在纳米ZnO的表面，纳米复合粒子为球形，大小均匀，且在PC基体中分散均匀；纳米复合粒子的加入使复合材料的耐光氧老化性能明显提高，而加热温度、注塑压力和保压压力降低。 |

| Abstract: | ZnO-SiO2 nanoparticles were obtained by depositing SiO2 layer through TEOS hydrolysis on the surface of nano-ZnO,and they were added into polycarbonate(PC) matrix to modify PC. The surface coating effect on nano-ZnO was investigated,the anti-photodegradation properties of composites with different content of nanoparticles were tested,and the effects of nanoparticles on the injection molding parameters of composites were discussed. The results indicated that SiO2 was successfully deposited on the surface of ... |
