Asymmetric Fe@CNTS/Ag@CNTA Integrated Carbon Nanotube Frameworks for High-Efficiency and Low-Reflection Electromagnetic Interference Shielding

This study presents an asymmetric Fe@CNTS/Ag@CNTA integrated framework that achieves ultrahigh, absorption-dominated electromagnetic interference shielding (111 dB) with minimal reflection by utilizing a gradient magnetic-loss layer and a conductive internal boundary to create direction-dependent, anisotropic wave attenuation.
