AB - Carbonyl iron powder (CIP) is a conventional magnetic loss absorbing material that can effectively mitigate the reflection and scattering of radar waves. In this work, zinc acetate and sodium hydroxide were utilized as raw materials, and the hydrothermal method was employed to prepare nano-grade zinc oxide-coated carbonyl iron powder composite (CIP/ZnO). CIP/ZnO composites with different contents of ZnO were subjected to XRD, SEM, and FT-IR detection analyses; the electromagnetic properties and the microwave absorption properties of samples with different thicknesses were tested. The coating of ZnO on CIP can enhance the permittivity of CIP, decrease its permeability, reduce reflection loss, and improve its absorption performance in the high-frequency band, enabling the material to achieve better absorption performance under a thinner condition. At a thickness of 1.2 mm, the minimum reflection loss of the CIP/ZnO composite material is − 27.8 dB, the corresponding frequency is 17.3 GHz, and the effective absorption bandwidth is 10–18 GHz. In addition, the anti-oxidation property of the composite materials has witnessed a remarkable enhancement, effectively facilitating the practical application of carbonyl iron powder in high-temperature settings.
