| 摘 要： | 以膨胀石墨和硫酸亚铁为前驱物,采用一步还原法得到Fe/膨胀石墨(Fe/EG)插层复合物.并用SEM、XRD、网络矢量分析仪等测试仪器分别研究了Fe含量(wFe)对Fe/EG插层复合物的形貌、结构、微波电磁和吸波性能的影响.结果表明:改变插层剂Fe的含量能有效地调控Fe/EG插层复合物的微波电磁与吸收特性.随wFe在27.5wt%～71.5wt%范围内增大,Fe/EG插层复合物的介电常数在wFe=27.5wt%时达到最大值,磁导率呈现多重共振现象,微波吸收性能逐渐增强.这种优异的微波吸收特性归功于Fe/EG插层复合物增强的电磁匹配和磁共振损耗.

| Abstract: | Using expanded graphite and FeSO4 as precursor,Fe/expanded graphite (Fe/EG) intercalation compounds were prepared by a facile one-step reduction approach.The influences of Fe nanoparticles content wFe on the morphology,structure,and microwave electromagnetic and absorbing properties of the corresponding intercalation compounds were studied by SEM,XRD,and network vector analyzer,respectively.The results showed that the change of wFe could effectively tune the microwave electromagnetic and absorbing character... |
