Dual magnetic particles modified carbon nanosheets in CoFe/Co@NC heterostructure for efficient electromagnetic synergy

Soft Science, Journal Year: 2024, Volume and Issue: 4(4)

Published: Nov. 30, 2024

Dual magnetic particles-modified carbon materials have great potential in terms of ultrathin thickness (≤ 2 mm) and super electromagnetic wave (EMW) absorption -70 dB). Herein, using CoFe-metal-organic framework (MOF)-derived CoFe/Co@NC heterostructures composed hollow CoFe nanospheres, solid Co nitrogen-doped (NC) nanosheets, we demonstrate how the dual particles regulate response behavior heterostructure thus steer efficient EMW performance. That is, inherits an ultra-strong reflection loss (R L) -73.8 dB at 1.78 mm. The effective bandwidth (EAB) value is also available up to 5.4 GHz. Moreover, computer simulation technology (CST) simulations reveal good radar stealth effect heterostructures. Experimentally, outstanding due a large number heterointerfaces, conductive networks nanoparticles, which bring considerable interface polarization, conduction loss, characteristics. These findings underscore importance synergy induced by for steering absorbers.

B─C Bonding Configuration Manipulation Strategy Toward Synergistic Optimization of Polarization Loss and Conductive Loss for Highly Efficient Electromagnetic Wave Absorption

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 9, 2024

Abstract In non‐metallic atom‐doped carbonaceous materials, the disparity in electronegativity between doped constituents and carbon atoms predetermines bonding topology of covalent bonds distribution electron density. This, consequently, influences polarization transport behavior within domain electromagnetic wave attenuation attributes material. However, influence formed by doping with weakly electronegative on density distribution, effects, remains uncharted. To address this deficiency, study fabricates a porous material (NCP) incorporates boron‐doped to form tunable B─C configurations (B‐NCP). By modulating configuration proportion, it is feasible achieve synergistic optimization conductive loss B‐NCP specimen. The optimized prototype ‐1200 sample displays exceptionally efficient absorption capabilities minimum reflection (RL min ) −52.03 dB an effective bandwidth (EAB) 5.36 GHz. This presents conscientious model for comprehending mechanisms associated atom carbon‐based wave‐absorbing materials.
