Lightweight Ni Foam‐Based Ultra‐Broadband Electromagnetic Wave Absorber

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(30)

Published: May 18, 2021

Abstract Skin effect and high density are the main reasons that restrict search of lightweight high‐performance metal‐based electromagnetic (EM) wave absorbing materials. Although nanostructured metal materials have been fabricated to solve above problems, poor dispersibility chemical stability issues brought about by surface energy due existing nano‐size effect. In this work, Ni foam with NiO/NiFe 2 O 4 in situ growth composites a facile universal route as an effective alternative EM absorber. Impressively, it is found structure /Ni components can synergistically boost absorption capacity. detail, impedance matching from dissipation interfacial polarization defect induced provided mainly contributes its ultra‐broadband performance. As result, as‐prepared sample (0.06 g·cm −3 ) delivers wide bandwidth 14.24 GHz thin thickness 0.6 mm, well as, specific 19444.4 GHz·g −1 ·cm −2 . This work sheds light on novel view synergistic behaviors demonstrates new pathway for preparation absorbers.
