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 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.

薄而柔软的Fe–Si–B / Ni–Cu–P金属玻璃多层复合材料,可有效屏蔽电磁干扰

迫切需要能够提供有效的电磁干扰(EMI)屏蔽的薄而柔软的材料,尤其是如果它们易于加工并能承受恶劣环境的话。在这里,层状结构的Fe–Si–B / Ni–Cu–P金属玻璃复合材料是通过在商用Fe–Si–B金属玻璃上进行简单的化学镀Ni–Cu–P涂层而开发的。厚度为0.1 mm的复合材料在X波段频率范围内显示40 dB的EMI屏蔽效果,高于传统金属,金属氧化物及其较大厚度的聚合物复合材料的EMI屏蔽效果。事实证明,大多数施加的电磁波都被吸收了,而不是反弹回来。此性能源自优异的软磁性能,出色的导电性,以及多层复合材料的多次内部反射。此外,柔性复合材料还具有良好的耐腐蚀性,高的热稳定性和出色的拉伸强度,使其适用于恶劣的化学或热环境中的EMI屏蔽。
