One‐Click to 3D: Helical Carbon Nanotube‐Mediated MXene Hierarchical Aerogel with Layer Spacing Engineering for Broadband Electromagnetic Wave Absorption

Small Methods, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 28, 2024

Abstract MXenes are 2D materials known for their unique electromagnetic wave absorption (EMWA) properties arising from varied composition and structure. In this study, a one‐step ice‐assisted process is utilized to directly transform MXene into 3D single‐layer aerogels (SMAs). Furthermore, the interlayer spacing of SMAs optimized by incorporating helical carbon nanotubes (HCNTs). Because van der Waals interaction between nanosheets HCNTs, assembled HCNT@MXene (HMAs) exhibited regular porous structure moderate conductivity, leading significantly enhanced responses, as demonstrated finite element simulation. The HMAs showed an exceptional EMWA, with minimum reflection loss −51.45 dB effective bandwidth 6.48 GHz at 3.0 wt.% filler ratio. Additionally, visualization surface charge distribution power density characteristics clarified underlying EMWA mechanisms. By employing hollow gradient metamaterial design, further expanded 13.98 GHz. maximum radar cross‐section reduction values 27.08 m 2 . Moreover, excellent thermal insulation capability. This paper presents straightforward yet method fabricating offers valuable insights development application MXene‐aerogel‐based EMW absorbers.
