The development of thin semiconductor nanomaterial sulfide absorbers with strong absorption and a wide bandwidth can effectively expand the application of sulfide in the field of electromagnetic wave absorption. Structural analysis of the crystallographic information, epitaxial elemental information, microscopic morphological structure information, electromagnetic wave parameter information, and radar scattering cross-sectional area characteristics of Cu 9 S 5 demonstrated that the morphological regulation strategy applied to Cu 9 S 5 nanomaterials achieved the expected results. The crystalline shape of the nanomaterial was pure. The prepared Cu 9 S 5 nanomaterial had multiple electromagnetic wave loss mechanisms. Among them, the minimum reflection loss of the polyhedral Cu 9 S 5 nanomaterial was −60.77 dB at 1.78 mm, and the effective absorption bandwidth of the porous sheet Cu 9 S 5 nanomaterial reached 5.2 GHz at 1.9 mm. This work provided a strategy for the application of semiconductor Cu 9 S 5 functional nanomaterials in the field of electromagnetic wave absorption and can serve as a basis for subsequent in-depth studies on semiconductor metal sulfides. Nanostructured Cu 9 S 5 has excellent research prospects in the field of microwave absorption.

Radar, which is an electronic and electromagnetic system that works with the use of radio waves to detect and locate objects, has led to the need for radar absorber materials for some military applications, especially for defence and security. In this study, barium hexaferrite and copper powders were used to investigate a radar absorbing composite material. Barium hexaferrite powders were synthesized by Sol-Gel method. Barium hexaferrite and copper powders were added to a polyurethane resin at different loading levels to interpolate the radar absorption property. Metal substrates were covered with these polymeric composite materials. Characterization tests such as X-Ray Diffraction, Scanning Electron Microscopy (SEM) and scratch test were performed. For evaluating the radar absorbing properties of reinforced composites, a Network Analyzer was used. It was concluded that use of barium hexaferrite and copper powders improved absorbing activity of the coatings. Increasing the amount of barium hexaferrite and copper powders in the coatings, increased the radar absorption performance. Besides, very good synergistic effects were obtained in between barium hexaferrite and Cu powders. The reason for this is thought to be their own individual magnetic properties and electrical that work in the radar absorption mechanism.

“…67 Finally, metal matrix absorbers are multiphase materials composed of ductile metal or alloy, which could also implant some nanosized reinforcement materials. Guo et al 68 prepared an excellent metal matrix iron/cobalt/carbon EMWA nanocomposite through electrospinning and the heat-treatment method. The results indicated that the combination of magnetic metal particles and carbon components could achieve an optimal wave absorption performance, while accompanied with high-temperature resistance.…”

With the increasing problems of electromagnetic interference and electromagnetic radiation, electromagnetic wave absorption (EMWA) materials have received considerable attention in civil and military fields. Among various EMWA materials, one-dimensional (1D) nanomaterials are recognized as a very promising candidate because of their unique aspect ratio, special shape anisotropy, large specific surface area, and simple manufacturing process. Herein, this paper presents a comprehensive review of recent research progress of 1D nanomaterials for EMWA applications, with a special focus on the advances in general preparation strategies and microscopic structure construction. Furthermore, the current challenge and future prospect of 1D electromagnetic absorbers are proposed, which should provide some guidelines for the design of advanced EMWA materials.
