To reduce escalating electromagnetic pollution from modern technologies, advanced composites exhibiting thinness, light weight, broad bandwidth, and strong electromagnetic wave absorption (EWA) are urgently required. In this work, epoxy nanocomposites incorporating 0-D Fe₃O₄@PANI and 2-D graphene (Gr) as functional fillers were prepared via hot-pressing method. When the mass ratio of 120:1 (Fe₃O₄@PANI: Gr) nanocomposite exhibits a minimum reflection loss of - 54.86 dB and an effective absorption bandwidth of 2.27 GHz. Meanwhile, Radar Cross Section (RCS) reduction value can even reach 33.26 dB m². This work provides a scalable idea for preparing epoxy nanocomposites with excellent EWA performance.
