We here report a facile method to fabricate a sponge-supported reduced graphene oxide aerogel (S-RGOA) using a commercial melamine sponge and graphene oxide (GO). Firstly, GO sheets were self-assembled within the melamine sponge by the assistance of a chemical cross-linking agent; and then, freeze-drying and thermal treatment were adopted to prepare S-RGOA, in which continuous porous reduced graphene oxide (RGO) network formed between the skeleton. The resulting S-RGOA exhibited a high electromagnetic interference shielding effectiveness (EMI SE) of 20.4-27.3 dB in 8-12 GHz and the specific EMI SE could reach 1437 dB.cm(3)g(-1). The mechanical test suggests that the lightweight S-RGOA is compressible and possesses low energy dissipation. Burning and TGA measurements indicate that S-RGOA is fire-resistant and has excellent thermal stability. Our work provides an economical and environmentally-friendly method to fabricate RGO aerogels for using as electromagnetic interference materials.
