With rapid technological advancements, electromagnetic radiation is becoming one of new forms pollution, which not only affects the use precision instruments, but also threatens safety human life. Electromagnetic wave (EMW) absorbing material can effectively attenuate EMW, among carbon fiber doped magnetic particles possess low density, multiple attenuation, and magnetic-dielectric synergy, attracting more attention. Carbon-based fibers achieve combination loss dielectric loss, improve impedance match, resulting in excellent reflection (RL) effective absorption bandwidth (EAB). Herein, recent researches on carbon-based are reviewed, focusing preparation methods structural difference. It specifically introduces their performance advantages, providing a brief analysis structure-property relationship. Finally, extensive application potential emphasize, highlighting challenges opportunities field EMW absorption.

Abstract Microwave absorption materials (MAMs) are originally developed for military purposes, but have since evolved into versatile with promising applications in modern technologies, including household use. Despite significant progress bench‐side research over the past decade, MAMs remain limited their scope and yet to be widely adopted. This review explores history of from first‐generation coatings second‐generation functional absorbers, identifies bottlenecks hindering maturation. It also presents potential solutions such as exploring broader spatial scales, advanced characterization, introducing liquid media, utilizing novel toolbox (machine learning, ML), proximity lab end‐user. Additionally, it meticulously compelling medicine, mechanics, energy, optics, sensing, which go beyond efficiency, along current development status prospects. interdisciplinary direction differs previous primarily focused on meeting traditional requirements (i.e., thin, lightweight, wide, strong), can defined next generation smart absorbers. Ultimately, effective utilization ubiquitous electromagnetic (EM) waves, aided by third‐generation MAMs, should better aligned future expectations.

Ti3C2Tx MXene shows great potential in the application as microwave absorbers due to its high attenuation ability. However, excessively permittivity and self-stacking are main obstacles that constrain wide range of applications. To tackle these problems, herein, microspheres SiO2@Ti3C2Tx@CoNi with hydrangea-like core–shell structure were designed prepared by a combinatorial electrostatic assembly hydrothermal reaction method. These constructed an outside layer CoNi nanosheets intermediate wrapping on core modified SiO2, engendering both homogenous heterogeneous interfaces. Such trilayer "magnetic microsize supercapacitors" can not only induce dielectric loss magnetic but also provide multilayer interfaces enhance interfacial polarization. The optimized impedance matching could boost reflection (RL) electromagnetic synergy. synthesized demonstrate outstanding absorption (MA) performance benefited from advantages. obtained RL value was −63.95 dB at ultra-thin thickness 1.2 mm, corresponding effective bandwidth (EAB) 4.56 GHz. This work demonstrates designing strategy is highly efficient for tuning MA MXene-based microspheres.

Abstract To tackle the increasingly complex electromagnetic (EM) pollution environment, application‐oriented wave (EMW) absorption materials with ultra‐thin, light weight and strong tolerance to harsh environment are urgently explored. Although graphene aerogel‐based lightweight EMW absorbers have been developed, thinner thickness more effective polarization loss strategies still essential. Based on theory of transmission, this work innovatively proposes a high attenuation design strategy for obtaining ultra‐thin materials, cobalt selenide (CoSe 2 ) is determined as animportant part absorbers. In order obtain dielectric parameter range that satisfies characteristics improve properties composite CoSe modified N‐doped reduced oxide (N‐RGO/CoSe designed. Meanwhile, controllable introduction defect engineering into RGO can activate Schottky heterointerfaces composites generate interfacial effect, achieving while significantly improving EM capability. addition, infrared thermal images anti‐icing experiments show has good corrosion resistance, stealth, insulation properties. Therefore, provides an thin‐thickness, light‐weight, high‐performance embodying advantages N‐RGO/CoSe in practical applications.
