abstract = {The accelerated growth of modern electronics and devices has drawn considerable attention for the exploration and fabrication of innovative electromagnetic interference (EMI) shielding materials. Due to its layered porous architecture and distinctive characteristics, graphene aerogel is considered an appropriate candidate for advanced EMI shielding materials. Nonetheless, developing effective EMI shielding materials from graphene aerogel is challenging due to its moderate electrical conductivity. In this study, motivated by the concept of dielectric-magnetic synergy strategy, we present a graphene aerogel incorporating CoFe2O4 nanoparticles (NPs) and Ag nanowires (NWs) as enhancements. The CoFe2O4 NPs/Ag NWs/graphene aerogel, benefiting from the synergistic effects of CoFe2O4 NPs, Ag NWs, and graphene aerogel, demonstrated exceptional EMI shielding capabilities. Specifically, the CoFe2O4 NPs/Ag NWs/graphene aerogel (5 mm) offered an optimal shielding effectiveness of 67.4 dB, which was 247% of the graphite aerogel. Meanwhile, it exhibited a remarkable low density of 0.048 g/cm3 and a high specific shielding effectiveness value of up to 1291.67 dB·cm3/g. In addition, it also showed superior Joule heating performance and hydrophobicity.}
