| 中文摘要: |
| 采用偶联剂交叉处理法,成功地在碳纤维表面接枝了纳米 SiO2 粒子。 对制备过程中各步获取的样品进行了表面形貌表征和傅里叶红外光谱分析,并讨论了纳米 SiO2 的浓度、反应温度和时间等实验条件对接枝效率的影响。 结果表明:当纳米 SiO2 的浓度为 4% ,反应温度为 100 ℃ ,反应时间为 4 h 时,接枝效果最佳,接枝率为 5 . 69% 。 |
| 英文摘要: |
| Nano-silica were grafted onto the surface of CF by the cross reaction of silane-coupling. In order to investigate the best modification condition, the effects of the content of nano-silica, reaction time and temperature were studied. The surface morphology of the modified samples during the preparation were characterized and the structures of them were analyzed by FTIR. The results showed that the best modification conditions obtained were as follows: the SiO2content was 4 % , reaction temperature was 100 ℃ and reaction time was 4 h. Under optimum conditions, the grafting rate of Nano-SiO2was 5 . 69 % . |
