摘 要：Thin and flexible materials that can provide efficient electromagnetic interference（EMI） shielding are urgently needed, especially if they can be easily processed and withstand harsh ***, layer structured Fe–Si–B/Ni–Cu–P metallic glass composites have been developed by simple electroless plating Ni–Cu–P coating on commercial Fe–Si–B metallic *** 0.1-millimeter-thick composite shows EMI shielding effectiveness of 40 dB over the X-band frequency range, which is higher than that of traditional metals, metal oxides and their polymer composites of larger *** of the applied electromagnetic waves（EMWs） are proved to be absorbed rather than bounced *** performance originates from the combination of superior permeability, excellent electrical conductivity, and multiple internal reflections from multilayer *** addition, the flexible composites also exhibit good corrosion resistance, high thermal stability, and excellent tensile strength, making them suitable for EMI shielding in harsh chemical or thermal environments.
