摘要

A bamboo-inspired Al-Fe₃O₄/aramid nanofibers/poly(3,4-ethylenedioxythiophene) nanocomposite film with a through-thickness gradient architecture was constructed via scalable vacuum-assisted filtration. Gradient-regulated magnetic-dielectric coupling and percolative conductive networks enabled strong impedance matching and efficient electromagnetic attenuation across the gigahertz (GHz)-terahertz (THz) bands. An outstanding reflection loss (− 56.6 dB at 2.2 mm), broadband absorption (3.5 GHz), high electromagnetic interference shielding effectiveness (42.0 dB in GHz and 57.8 dB in THz), and reduced radar cross section were achieved.
