| Abstract | In this study, highly effective organic-inorganic composites Fe/C/PPy (Fe/C nanocapsules embedded in polypyrrole) were prepared by combining the arc-discharge process and in situ oxidative polymerization method. It was found that Fe/C/PPy-paraffin composites have higher dielectric loss in comparison with both Fe/C-paraffin and PPy-paraffin composites, implying enhanced dielectric properties by this embedded structure. The RL (reflection loss) exceeding -10 dB is obtained in the 11.2-16.9 GHz for a given thickness of 2.2 mm, which covers most of the Ku-band (12-18 GHz). The RL exceeding 10 dB is obtained in the 9.6-14.1 GHz for a given thickness of 2.5 mm, which covers most of the X-band (8-12 GHz). The illustration of the physical model indicated that the special embedded structure with abundant heterogeneous interfaces is responsible for the excellent microwave-absorption performances. |
