With the rapid development of fifth-generation mobile communication technology and
wearable electronic devices, electromagnetic interference and radiation pollution caused by
electromagnetic waves have attracted worldwide attention. Therefore, the design and
development of highly efficient EMI shielding materials are of great importance. In this work,
the three-dimensional graphene oxide (GO) with regular honeycomb structure (GH) is firstly
constructed by sacrificial template and freeze-drying methods. Then, the amino …
