摘要

Graphene nanosheet (GN) filled BaTiO3 ceramics with high-performance electromagnetic interference (EMI) shielding were prepared via pressureless sintering. Both the real and imaginary parts of the complex permittivity increased with increasing GN content. The EMI shielding results showed that the absorption mechanism is the main contributor to the total EMI shielding effectiveness (SE). The total EMI SE is greater than 40 dB in the X-band at 1.5 mm thickness, which suggests the GN-BaTiO3 ceramics could be good candidates for highly efficient EMI shielding materials in the whole X-band.
