Abstract

The escalating demand for high-performance applications, such as drones, smart wearables, and military communication systems, is increasingly challenged by extreme conditions, including high temperatures, humidity, and intense electromagnetic interference. Overcoming these obstacles requires advanced electromagnetic wave (EMW) absorbing materials with exceptional environmental adaptability. In this work, we introduce a multifunctional and efficient EMW absorber (i.e., CMF/HEA), which combines lightweight, thermal insulation, and hydrophobic properties. The unique integration of carbonized melamine foam (CMF) with magnetic high-entropy alloy (HEA) nanosheets not only provides a lightweight framework but also enhances EMW attenuation due to the inherent lattice distortion and high-entropy effects of the HEA nanosheets. This combination achieves a remarkable minimum reflection loss (RL) of -74.86 dB and an effective absorption bandwidth (EAB) of 7.94 GHz with only 12 wt% filling, maintaining a low material density. Additionally, the composite exhibits excellent thermal insulation and hydrophobicity, featuring thermal camouflage and a water contact angle of 130°, ensuring device stability under extreme conditions. Simulation results demonstrate that the CMF/HEA not only optimizes impedance matching but also introduces a multi-scale absorption mechanism, offering a novel and versatile approach to EMW absorption for complex practical applications.

期刊介绍： Nano Energy is a multidisciplinary, rapid-publication forum of original peer-reviewed contributions on the science and engineering of nanomaterials and nanodevices used in all forms of energy harvesting, conversion, storage, utilization and policy. Through its mixture of articles, reviews, communications, research news, and information on key developments, Nano Energy provides a comprehensive coverage of this exciting and dynamic field which joins nanoscience and nanotechnology with energy science. The journal is relevant to all those who are interested in nanomaterials solutions to the energy problem. Nano Energy publishes original experimental and theoretical research on all aspects of energy-related research which utilizes nanomaterials and nanotechnology. Manuscripts of four types are considered: review articles which inform readers of the latest research and advances in energy science; rapid communications which feature exciting research breakthroughs in the field; full-length articles which report comprehensive research developments; and news and opinions which comment on topical issues or express views on the developments in related fields.
