 This research has developed a new type of EMI shielding material based on three-dimensional graphene oxide, GO, with regular honeycomb structure, GH, amino-functionalized faini alloy particles, F-faini, and epoxy resin. The resulting RGH at faini slash epoxy composites show excellent EMI shielding performance, thermal stability, and mechanical properties. This study provides a promising approach for developing efficient EMI shielding materials. This article was authored by Ping Song, Zhong Lai Ma, Huaciu, and others.
