摘要: The composites of nanoparticles magnetic metals Co, Ni, and Ni–Fe dispersed on the nanolayers expanded graphite (EG) were prepared by impregnation EG with ethanol solutions metal acetates, followed drying reduction in H2. Such combined properties high electric conductivity conductivities metals, thus exhibited shielding effectiveness a wide range frequencies. Specifically, composite containing 30%Ni 70%EG reached 70–105dB at frequencies from 300kHzto1.5GHz.
