Lightweight and Flexible Graphene Foam Composites for High-Performance Electromagnetic Interference Shielding

A lightweight graphene foam composite with a density of 0.06 g/cm3 is developed. It shows a EMI shielding effectiveness of 30 dB and specific shielding effectiveness of 500 dB·cm3/g, which surpasses the best values of metals and other carbon‐based composites. In addition, the excellent flexibility o...

More Information
Summary:A lightweight graphene foam composite with a density of 0.06 g/cm3 is developed. It shows a EMI shielding effectiveness of 30 dB and specific shielding effectiveness of 500 dB·cm3/g, which surpasses the best values of metals and other carbon‐based composites. In addition, the excellent flexibility of this foam composite gives it a stable EMI shielding performance under repeated bending.
