A review of 1D magnetic nanomaterials in microwave absorption

Microwave absorption (MA) materials are widely used in military and civilian applications to solve electromagnetic wave absorption and attenuation problems. The generation of high-performance materials containing extensive absorption frequency, strong absorption capacity and light weight has become a research focus in the field of MA. Magnetic materials have a wide range of applications due to their intrinsic ferromagnetic resonance absorption capacity. In addition to the inherent electromagnetic properties, the microstructure and morphology of the absorption material also have important influences on the electromagnetic wave absorption properties. One-dimensional (1D) nanostructure is considered to be beneficial microscopic morphology due to their unique shape anisotropy. The high aspect ratio is conducive to electron conduction and further increases the conduction loss capability. This review introduced the research progress of 1D magnetic nanomaterials in MA and categorized them from the viewpoint of preparation methods. Challenges and prospects were proposed toward the development of 1D magnetic nanomaterials in MA, which indicated the directions and priorities for future research.
