High entropy alloys (HEA) have garnered significant attention in electromagnetic wave (EMW) absorption due to their efficient synergism among multiple components and tunable electronic structures. However, high density limited chemical stability hinder progress as lightweight absorbers. Incorporating HEA with carbon offers a promising solution, but synthesizing stable HEA/carbon composite faces challenges the propensity for phase separation during conventional heat treatments. Moreover, EMW mechanisms HEAs may be different from established empirical models high-entropy effect. This underscores urgent need synthesize absorbers uncover intrinsic mechanisms. Herein, we successfully integrated quinary FeCoNiCuMn into honeycomb-like porous nanofiber (HCNF) using electrostatic spinning Joule-heating method. Leveraging inherent lattice distortion effects honeycomb structure, HCNF/HEA demonstrates outstanding properties at an ultralow filler loading of 2 wt %. It achieves minimum reflection loss −65.8 dB boasts maximum bandwidth up 7.68 GHz. study not only showcases effectiveness combining HCNF HEA, also potential synthesis developing HEA-based
