Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>Three-dimensional flower-like <italic>α</italic>-Fe₂O₃ structures were grown on the surface of ordered mesoporous carbon nanorods through a facile hydrothermal method, and their electromagnetic (EM) parameters were measured at 2–18 GHz. The special geometric morphology and proper magnetic loss of <italic>α</italic>-Fe₂O₃ nanoparticles and the strong dielectric polarisations and relaxations in the composites contribute to its excellent EM wave absorption. A reflection loss exceeding −10 dB was obtained at 9·9–16·1 GHz for an absorber of 50 wt-% loading with 2·50 mm thickness layer. The result provides a novel EM wave absorbing material to meet the practical applications.</p> </abstract>
