Abstract

Lightweight, versatile, and efficient electromagnetic wave absorption materials (EWAMs) are needed to counteract the adverse electromagnetic pollution caused by electromagnetic radiation leakage from electronic devices and to eliminate electromagnetic interference. The hybrids of high entropy systems/carbon materials with multifarious loss mechanisms exhibit a tendency to become the focus of the next generation of EWAMs. Here, we fabricate hierarchical porous FeCoNiCrAl/CNF nanocomposites by a one-step microwave instantaneous heating method. Its remarkable microwave absorption performance benefits from the unique nanosize effect of FeCoNiCrAl high-entropy alloy (HEA) nanoparticles in the composition and the multicomponent synergy and hierarchical pore structure. These results provide guidance for the design of advanced HEA-based EWAMs.
