Liquid Metal-Ionogel Core–Shell Fibers for Reflection-Suppressed Electromagnetic Interference Shielding and Strain Sensing

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 28, 2025

Electromagnetic interference (EMI) shielding fibers are crucial in practical uses for their flexibility and one-dimensional form. However, application is limited by poor compatibility between EMI components fiber substrates, high electromagnetic wave reflectivity. Herein, a core/shell-structured introduced, featuring core of Ga-In-Sn-Zn alloy, Carbopol, air bubbles, shell ionogel formed from copolymerized acrylamide acrylic acid. A single achieves total effectiveness ∼35 dB within the 2-18 GHz range, which increases to ∼70 when three stacked. Remarkably, demonstrates enhanced performance following stretching recovery. Additionally, it exhibits excellent impedance matching, with reflection power coefficient as low 0.14 at 10 GHz. The fiber's mechanism encompasses shielding, absorption shielding─attributable conduction loss polarization loss─and multiple shielding. Furthermore, shows potential strain sensor. This research offers an effective strategy creating flexible capabilities EM reflection.

Published: April 30, 2025

Abstract Achieving effective electromagnetic wave (EMW) absorption performance with less than 2 mm remains a significant challenge in developing EMW materials. Herein, Fe atoms embedded into NH 3 ‐treated 3D porous graphene (3DPG‐NH ‐Fe) are synthesized via simple method of ion impregnation for efficient absorption. The process enables the formation specific pyrrole‐N dopants 3DPG, which provide anchoring sites complexing to construct FeN x moieties. Compared pristine 3DPG‐NH ‐Fe exhibits remarkable characteristics, achieving minimum reflection loss (RL) −56.35 dB and an bandwidth (EAB) 4.45 GHz at low filler loading wt.% thin thickness 1.4 mm, exceeding most reported graphene‐based outstanding is critically attributed incorporation coordinated by strong orbital hybridization N‐p y Fe‐3d x2‐y2 graphene, not only produces additional dipoles but also generates high spin atomic magnetic moment, thus enhancing both dielectric EMW. This work demonstrates new route modulating characteristics achieve
