| 摘 要： | 选用乙烯-丙烯酸酯-甲基丙烯酸缩水甘油酯(E-MA-GMA)三元共聚物对纳米SiO2表面进行修饰包覆改性，考察改性后纳米SiO2在聚对苯二甲酸丁二醇酯(PBT)基体中的分散情况及对PBT复合材料力学性能的影响。FTIR、TEM、SEM结果表明，E-MA-GMA的环氧基团与纳米SiO2的—OH 基团发生反应，破坏了SiO2的链状团聚结构，降低了纳米粒子间氢键等作用力。质量分数为10%～20% E-MA-GMA 改性的纳米SiO2在PBT基体中的分散性及其与基体的相容性均得到明显改善，从而提高了PBT基复合材料的弯曲和拉伸性能。与纯PBT相比，SiO2/PBT复合材料的拉伸强度提高了9%，而弯曲强度和模量分别提高了14%和20%。

| Abstract: | Nano-SiO2 was firstly modified by coating with ethylene-methyl acrylate-glycidyl methacrylate(E-MA-GMA) elastomer through the direct solvent process,and the dispersion of nano-SiO2 in PBT and the effects of modified nano-SiO2 on the properties of PBT were investigated.FTIR,TEM and SEM results indicate that the epoxy group of E-MA-GMA can react with the hydroxyl groups of the silica surface to destroy the aggregation of SiO2 and reduce the interactions between the nano-SiO2 particles;SEM results show that th... |
