Reduced Graphene Oxides: Light‐Weight and High‐Efficiency Electromagnetic Interference Shielding at Elevated Temperatures

Abstract
Chemical graphitized r‐GOs, as the thinnest and lightest material in the carbon family, exhibit high‐efficiency electromagnetic interference (EMI) shielding at elevated temperature, attributed to the cooperation of dipole polarization and hopping conductivity. The r‐GO composites show different temperature‐dependent imaginary permittivities and EMI shielding performances with changing mass ratio.
