Abstract
Lightweight graphene nanoplatelet (GNP)/boron carbide (B4C) composites were prepared and the effect of GNPs loading on the electromagnetic interference (EMI) shielding effectiveness (SE) has been evaluated in the X-band frequency range. Results have shown that the EMI SE of GNP/B4C composite increases with increasing the GNPs loading. An EMI SE as high as 37 ∼ 39 dB has been achieved in composite with 5 vol% GNPs. The high EMI SE is mainly attributed to the high electrical conductivity, high dielectric loss as well as multiple reflections by aligned GNPs inside the composite. The GNP/B4C composite is demonstrated to be promising candidate of high-temperature microwave EMI shielding material.

Conducting polymer composites can be obtained by incorporating high aspect ratio conductive nanofillers, such as carbon nanotubes (CNTs), carbon nanofibers (CNFs), metal nanowires (MNWs), and graphene nanoplatelets (GNPs).[2,3,4,5,10,11,12,13,14,15]
