Ping Song et al.

Summary: With the rapid development of fifth-generation mobile communication technology and wearable electronic devices, the need for highly efficient EMI shielding materials has become crucial. In this study, a three-dimensional graphene oxide (GO) with regular honeycomb structure (GH) was constructed using sacrificial template and freeze-drying methods.
