Electromagnetic interference shielding of graphene/epoxy composites
Abstract.
Composites based on graphene-based sheets have been fabricated by incorporating solution-
processable functionalized graphene into an epoxy matrix, and their electromagnetic
interference (EMI) shielding studies were studied. The composites show a low percolation
threshold of 0.52 vol.%. EMI shielding effectiveness was tested over a frequency range of
8.2–12.4 GHz (X-band), and 21 dB shielding efficiency was obtained for 15 wt% (8.8 vol.%)
loading, indicating that they may be used as lightweight, effective EMI shielding materials.
