Tailored Electro-Magnetic-Porous Multigradient Nanoarchitectonics for Absorption-Dominated Electromagnetic Interference Shielding and Adaptive Multifunctionality.

ABSTRACT: Herein, a multifunctional electromagnetic interference (EMI) shielding membrane with a conductivity-permeability-pore size gradient structure is fabricated via shear-induced in situ fibrillation coupled with layer-by-layer assembly. Under intense shear, carbon nanotube (CNT) nanofibers intertwine with polytetrafluoroethylene (PTFE) nanofibrils to form an interpenetrating dual-nanofibrous network, which not only robustly anchors Fe₃O₄ nanoparticles but also establishing continuous conductive and thermal pathways. Moreover, the integration of this unique dual-nanofibrous structure with the intrinsic properties of its components endows the PTFE/CNT/Fe₃O₄-gradient (FCFe-G) membrane with superior mechanical properties, superhydrophobicity, flame retar
