  Abstract

Herein, Fe3O4 nanoparticles and graphene oxide (GO) are compounded first, followed by the addition of cellulose nanofiber (CNF) and l-ascorbic acid, to obtain Fe3O4@ reduced graphene oxide (rGO)/CNF foams via the freeze-drying method. The electrical conductivity and magnetism of as-prepared foams were improved due to the presence of rGO and Fe3O4, which is suitable for electromagnetic interference (EMI) shielding material. The results exhibit that Fe3O4@ rGO/CNF foams all possess a porous structure, and the optimized foam shows an EMI shielding effectiveness value of ~ 23 dB in the X-band. The good EMI shielding performance of the Fe3O4@ rGO/CNF foam originates from the synergy of its composition and structure. This work could provide a reference for the design and fabrication of novel EMI shielding materials.
