| Abstract | We propose and demonstrate a scheme to enhance microwave absorption property through mesoporous structure with high regularity. The mesostructured nanocomposites, embedding gamma-Fe2O3 within carbon matrix, exhibit a strong and broadband attenuation of microwave in the frequency range of 0.5-18 GHz, mainly due to the better impedance matching. C-2Fe-900 exhibits strong absorption characteristics with an absorption peak of -32.0 dB at 6.4 GHz. The absorption peak intensity and position can be adjusted by changing the matching thickness of the coating. Reflection loss below -10 dB (i.e., absorption above 90%) is obtained in the frequency range of 1.9-10.7 GHz. (C) 2011 Elsevier B. V. All rights reserved. |
