| 英文摘要 | Artificially designing and preparing composites with unique structure is one of important ways to effectively improve the electromagnetic wave absorption performance. In this study, binary flower-like WS2 /Co hybrid composites through anchoring WS2 nanoclusters on Co nanosheets have been successfully developed. Attributing to the hierarchical structure of the composites, the effective interfacial polarization verifying from distinct Cole-Cole semicircles could improve the dielectric loss substantially, also it enabled the multiple reflections of the incident waves which benefitted for promoting the energy dissipation. Furthermore, the host of lamellate Co could maintain the magnetic characteristic and supply the magnetic loss dominantly caused by natural and exchange resonance deriving from the high planar anisotropy, the guest of WS2 nanoclusters could induce dipole polarization deriving from vacancies of W and S atoms. As a result, excellent wave absorption performance could be achieved for the composites with the minimum RL (RLmin) of - 46.5 dB at 10.2 GHz under a small thickness of 1.7 mm, accompanied by a wide effective bandwidth (RL < -10 dB) covering from 2.7 to 18 GHz with integrated thicknesses from 1.0 to 5.0 mm. Prospectively, this work provides a new opportunity to fabricate the valuable materials for practical electromagnetic wave absorbing applications. (C) 2022 Elsevier B.V. All rights reserved. |
