Flexible Metamaterial Absorbers Based on Fe₃O₄-Doped Laser-Induced Graphene with Tunable Absorption Bands

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Due to widespread applications of electromagnetic waves (EMWs) in radar and communication systems, there is an urgent need for developing EMW absorbers capable working efficiently at multiple frequency points. In this work, flexible metamaterial (MAs) based on Fe3O4-doped laser-induced graphene (LIG/Fe3O4) are large-scale fabricated with the absorption bands tunable by regulating ferric chloride concentration laser path LIG/Fe3O4 meta-surface. The as-prepared triple band MA demonstrates superior S11 values -15.0 dB (9.0 GHz), -40.7 (12.2 -23.2 (16.8 respectively, attributed subwavelength units LIG/Fe3O4, synergistically combining dielectric magnetic loss. Moreover, MAs exhibit commendable corrosion resistance cross-section reduction characteristics, showing promising potential protection fields.

Composition design and property investigation of bismaleimide by branched crosslinking structure with low dielectric permittivity and high toughness

Polymers for Advanced Technologies, Год журнала: 2024, Номер 35(8)

Опубликована: Авг. 1, 2024

Abstract Due to the high‐power environments of electronic components, achieving exceptional dielectric properties and mechanical behavior necessary for packaging materials presents a significant challenge. In this study, trifunctional maleimide (HTMI) was synthesized by reacting hexamethylene diisocyanate trimer (HDI trimer) with Maleic anhydride (MA), followed preparation Bismaleimide (BMI) resin featuring micro‐branching structure through its reaction diallyl bisphenol A (DBA) ether BMI. The intentionally designed resulted in an increase free volume within BMI, leading 8.8% reduction constant. Additionally, architecture imparted superior BMI resin, as demonstrated 140% bending strength 149% impact cured product.
