High-Efficiency Electromagnetic Interference Shielding of rGO@FeNi/Epoxy Composites with Regular Honeycomb Structures

Ping Song et al.

Summary: With the rapid development of fifth-generation mobile communication technology and wearable electronic devices, the need for highly efficient EMI shielding materials has become crucial. In this study, a three-dimensional graphene oxide (GO) with regular honeycomb structure (GH) was constructed using sacrificial template and freeze-drying methods. Amino functionalized FeNi alloy particles (f-FeNi) were loaded onto the GH skeleton followed by in-situ reduction to prepare rGH@FeNi aerogel. The resulting rGH@FeNi/epoxy composites with a low rGH@FeNi mass fraction of 2.1 wt% exhibited a high EMI shielding effectiveness (EMI SE) of 46 dB, which is 5.8 times higher than that of rGO/FeNi/epoxy composites with the same mass fraction. The composites also displayed excellent thermal stability and mechanical properties.
