Construction of Hierarchical Carbon Fiber Aerogel@Hollow Co9S8 Polyhedron for High-Performance Electromagnetic Wave Absorption at Low-Frequency

In the continuously evolving era of science and technology, the development of effective electromagnetic wave absorbing materials with ideal characteristics such as low density, excellent microwave attenuation performance, pronounced real and complex permittivity and permeability, wide bandwidth, thin thickness, and efficient synthesis methods is paramount. This review paper aims to provide insight into the potential of carbonaceous materials, including carbon nanotubes (CNTs), reduced graphene oxide (rGO), and carbon fibers (CFs), for microwave absorption (MA) applications. Moreover, it highlights the MA properties of these subsets in their pristine form or composite form incorporated with polymers, metals, ferrites, and other materials for improving impedance matching and achieving desired features. In addition, variable morphologies such as hierarchal, porous, and hollow structures that provide large specific surface areas creating diversified loss mechanisms are discussed and reviewed. The paper concludes by addressing the challenges of fabricating microwave absorbers at an industrial level and the wide-scale incorporation in real-time application. Broadly, this review paper aims to serve as a reference for selecting MA composites with desired characteristics and a guide for future researchers in the field of electromagnetic absorbing materials.

Indirect bioleaching recovery of valuable metals from electroplating sludge and optimization of various parameters using response surface methodology (RSM).

The development of microwave absorption materials with good environmental adaptability is a hot topic in the electromagnetic protection field. In this research, Expanded graphite (EG)/ZIF-67 nanocubes-derived ([email protected]) composites were successfully fabricated by electrostatic assembly and subsequent heat treatment. The results show that the involvement of an appropriate content of [email protected] not only overcomes the problem of single EG impedance mismatch but also introduces additional magnetic loss for the absorber. At the thicknesses of 1.6 mm and 1.5 mm, an effective absorption bandwidth (EAB) of 4.52 GHz and a minimum reflection loss (RLmin) of -48.4 dB were achieved for the Z2-700 sample with a low filling ratio (20 wt%). The enhancement of EMW-absorption performance is attributed to the optimization of impedance matching and the synergistic action between multiple loss mechanisms. Electrochemical corrosion test showed that graphite nanoflakes of EG enhanced the transfer resistance during corrosion, and the corrosion resistance of pure [email protected] was enhanced with the protection of EG. This work provides a reasonable attempt to design and fabricate efficient microwave absorption materials suitable for harsh environments.
