Summary:The preparation of materials with extremely light weight and efficient electromagnetic interference (EMI) shielding performance is a great challenge for contemporary EMI shielding materials. Here, a simple one-step pyrolysis reduction method was used to simultaneously reduce the melamine foam (MF) and graphene oxide (GO) and silver salt adsorbed on the skeleton surface of MF to produce the carbonized melamine foam/reduced graphene oxide/Ag nanoparticles (CMF/RGO/Ag) foam. The density of CMF/RGO/Ag foam is 0.05 g cm −3 , which is ultra-low and achieves high EMI SE value of 55 dB. We believe that this study show a lightweight and high SE values EMI shielding materials fabricated by an effective method, and which demonstrate great potential to protect human and electronic devices from electromagnetic pollution.
