 Nicoldhs at ZnO nanorods were synthesized and subsequently heat treated to create Nico at C e slash ZnO composites. The resulting material exhibited excellent absorption properties, with a reflection loss of minus 60.97 dB at a thickness of 2.3 mm and a wideband absorption of 6.08 GHz at a thickness of 2.0 mm. This study demonstrates the potential of Ldhs as a promising material for microwave absorption applications. This article was authored by Jianwei Wang, Zheerwei Jia, Xuowalu and others.
