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 0.52vol.%. EMI shielding effectiveness was tested over a frequency range of 8.2–12.4GHz (X-band), and 21dB shielding efficiency was obtained for 15wt% (8.8vol.%) loading, indicating that they may be used as lightweight, effective EMI shielding materials.
