Lotus Leaf Derived NiS/Carbon Nanofibers/Porous Carbon Heterogeneous Structures for Strong and Broadband Microwave Absorption

Small, Journal Year: 2023, Volume and Issue: 19(50)

Published: Aug. 25, 2023

Developing composite materials with the synergistic effects of heterogeneous structures and multiple components is considered as a promising strategy to achieve high-performance electromagnetic wave (EMW) absorbers. To further satisfy demand broadband strong microwave absorption, novel NiS/carbon nanofibers (CNFs)/porous carbon successfully synthesized by hydrothermal chemical vapor deposition using lotus leaves biomass source. A few nanotubes (CNTs) uniformly dispersed Ni nanocrystals have also been found in hybrid. Benefiting from porous structure derived leaves, combination dielectric NiS, conductive nanomaterials, magnetic nanoparticles, together three-dimensional network CNFs CNTs, remarkable EMW absorption properties minimum reflection loss up -67.65 dB achieved at merely 2.32 mm. Besides, widest effective band can reach 5.9 GHz thin thickness 2.07 mm, covering almost entire Ku band. In addition, under incident angle 31°, radar cross-section reduction value LNSF-600 42.88 dBm2. Therefore, this work provides an efficient facile method for manufacturing outstanding biomass-derived

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.
