and flexible materials that can provide efficient electromagnetic
interference (EMI) shielding are urgently needed, especially if they
can be easily processed and withstand harsh environments. Herein,
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 glasses. The 0.1 mm-thick composite shows EMI shielding effectiveness
of 40 dB over the X-band frequency range, which is higher than those
of traditional metals, metal oxides, and their polymer composites
of larger thickness. Most of the applied electromagnetic waves are
proved to be absorbed rather than bounced back. This performance originates
from the combination of a superior soft magnetic property, excellent
electrical conductivity, and multiple internal reflections from multilayer
composites. In 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.
