| 中文摘要: |
| 利用FT-IR,SEM和矢量网络分析仪等对羰基铁粉改性前后的化学键特性、微观形貌和电磁参数等进行了研究,实验结果表明:硅烷偶联剂在羰基铁粉表面形成不均匀包覆层;羰基铁粉的电磁参数随硅烷偶联剂用量的增加而变化;根据电磁参数对材料的吸波性能进行计算,当乙烯基三甲氧基硅烷用量为2.0%(质量分数,后同)时,得到的吸波效果最好,5.2～ 10.0 GHz反射率均小于- 10 dB。 |
| 英文摘要: |
| The chemical-bond characteristic,micro-structure and electromagnetic parameters were investigated by means of FT-IR,SEM and vector network analyzer. The results show that the vinyltrimethoxysilane integrates asymme- try deposits on the surface of the carbonyl iron powder, the electromagnetic parameters are variable as the quantity of si- lane coupling agent increases. According to the electromagnetic parameters, the absorbing property of carbonyl iron powder was computed. When the quantity of vinyltrimethoxysilane is 2.0%, the radar absorbing property is best, the frequency range with reflectivity under- 10 dB is from 5.2 GHz to 10.0 GHz. |
