摘要: A simple liquid-reduction method to prepare the metallic particles/expanded graphite (EG) composites has been developed and electromagnetic shielding effectiveness (SE) of materials is studied. With this method, we have successfully implanted nanoparticles Ni, Cu, Ag into EG. It shown that their SE at low frequencies significantly increased by dispersing particles on EG, especially for 30% metal content. At frequency range 300 kHz–1 GHz, with surface density only 0.096 g/cm $^2$ , can reach as high 70–105 dB. Compared gained 17 dB kHz.
