With the rapid growth of electronics and telecommunication, there is an intensive requirement for developing electromagnetic interference (EMI) shielding technique to prevent malfunction of electronic equipment and threats to human health from electromagnetic (EM) waves. Herein, we demonstrate a multifunctional EMI shielding skin, which not only shows an excellent EMI shielding effectiveness (SE) but also can play a role as a pressure sensor. The EMI shielding skin consists of freestanding foam-structured graphene-reinforced poly (dimethylsiloxane) (PDMS) matrix. The graphene foam (GF) is decorated by Fe3O4 nanoparticles (NPs)-intercalated the Ti3C2TX nanosheets. The composite exhibits a remarkable average EMI SE of 80 dB in 8.2-12.4 GHz (X-band) and 77 dB in 26.5-40 GHz (Ka-band) due to excellent absorption SE. Furthermore, the lightweight, flexible, and highly conductive GF-based composites hold a promising sensing performance against the external pressure that opens up the possibility to use as the multifunctional EMI shielding skin for the wearable electronics and robotics.
