| 摘 要： | 采用在位分散聚合方法制备聚甲基丙烯酸甲酯 /二氧化硅微米级复合材料 ,讨论了不同表面性质的二氧化硅对材料拉伸性能、热性能、耐溶剂性能的影响 ,并用SEM、TG等手段研究了材料性能。结果表明 :由WD -70硅烷偶联剂处理过的二氧化硅微粒子填充的材料的各方面性能较好 ,由WD -10硅烷偶联剂处理过的二氧化硅填充的材料的拉伸性能次之 ,未经表面处理二氧化硅填充的材料的拉伸性能最差 ,后两者的热性能以及耐溶剂性能无明显差异

| Abstract: | The PMMA/SiO 2 composites was prepared by in-situ polymerization,and the properties of the composites filled by different-surface SiO 2 on mechanics,thermal stability and resistant solvent was study by the SEM,TG and so on.The conclusions reveal that the properties of the composites filled by SiO 2 modified by WD-70 are superior to that of the composites,no more difference on thermal stability,filled by Silica modified by WD-10 and unmodified silica,and the composites filled by unmodified silica is most bad on mechanics. |
