Abstract Metal‐organic framework (MOF)‐derived architectures are regarded as an effective electromagnetic wave (EMW)‐absorbing materials owing to their adjustable compositions and microstructures. The combination of MOFs with carbon nanofibers (CNFs) is a practical method increase the EMW absorption ability. In this work, cobalt‐based zeolitic imidazolate framework‐67 (ZIF‐67) serves self‐sacrificing precursor fabricate Co‐carbon nanofiber (Co‐CNF) composites via in situ electrospinning strategy. Comparative studies on ex situ, strategies for conducted. A unique structural evolution mechanism from ZIF‐67 Co nanoparticles explored. Numerous small evenly distributed surface synthesized Co‐CNF (in‐Co‐CNF) resulting collapse framework, whereas remains (ex‐Co‐CNF), encapsulating large nanoparticles. lower reflection loss ( RL ) −48.6 dB at 6.8 GHz 3.5 mm achieved in‐Co‐CNF because improved conduction, polarization, magnetic losses, ex‐Co‐CNF only exhibits −18.3 9.3 same thickness. radar cross‐section (RCS) simulation Tesla wireless transmission experiment conducted validate real applications.

Multifunctional Anisotropic Aerogels for Intelligent Electromagnetic Wave Absorption

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 26, 2024

Abstract The rapidly developing modern society has higher requirements for intelligent electromagnetic wave absorbing (EMA) materials than ever before. Herein, lightweight, multifunctional metal‐free carbon‐based aerogels (RCPs) with a longitudinal honeycomb porous framework and transverse neatly layered structure are obtained by heat‐treating graphene oxide/oxidized carbon nanotubes/hexachlorocyclotriphosphazene complex to simultaneously achieve the tunable EMA, flame retardancy, thermal insulation. anisotropic ensures properties of along tilt angles according environmental needs. effectively promotes multiple reflections scatterings waves compared structure, maximizing penetration inside material thus high EMA performance. optimized R 10 C 2 P‐4 exhibits minimum reflection loss in direction of−61.5 dB, while value is as low −22.4 dB direction. Furthermore, adequately inhibits spread heat, accompanied phosphorus species induced hexachlorocyclotriphosphazene pyrolysis, endowing good retardancy insulation conductivity 20.6 mW m −1 K direction, rather This work provides an ingenious insight into design materials, adapting flexibly various application requirements.
