Reduced Graphene Oxides: Light‐Weight and High‐Efficiency Electromagnetic Interference Shielding at Elevated Temperatures (Adv. Mater. 21/2014)

As the thinnest material of the carbon family, reduced graphene oxide (r-GO) composites exhibit highly efficient EMI shielding at elevated temperatures, attributed to the high carrier mobility coupled with abundant residual groups in/on the r-GOs, as described by W. Wang, H. Jin, M. Cao, and co-workers on page 3484. Meanwhile, due to the competition between the conductivity and relaxation, these composites with different mass ratios show opposite temperature dependences on both the imaginary permittivity and EMI shielding.
