| 摘 要： | 采用水下直流电弧放电法(DC arc-discharge in water)和化学气相沉积法(CVD)分别制备了单纯和内包金属纳米Fe颗粒的纳米洋葱状富勒烯(NOLFs). 用XRD、FESEM和HRTEM对两种产物的结构进行了表征和分析；用HP8722ES矢量网络分析仪测试了两种不同的NOLFs在2～18 GHz频率范围内的复介电常数和复磁导率, 并与石墨和活性炭进行了对比. 结果表明, 两种NOLFs都有较高的复介电常数和介电损耗; 内包金属纳米Fe颗粒的NOLFs有磁损耗.

| Abstract: | The hollow and Fe nanoparticle-encapsulated nano onion-like fullerenes (NOLFs) were synthesized respectively by DC arc-discharge in water and chemical vapor deposition (CVD). The microstructures of two products were characterized and analyzed by XRD, FESEM, and HRTEM. 2～18 GHz complex permittivity and complex permeability of different carbon materials, including NOLFs, graphite, and active carbon, were measured using HP8722ES vector network analyzer for comparison. The results showed that complex permittivity and dielectric loss of two NOLFs are higher; Fe nanoparticles-encapsulated NOLFs have magnetic loss. |
