With rapid development of 5G communication technologies, electromagnetic interference (EMI) shielding for electronic devices has become an urgent demand in recent years, where the development of corresponding EMI shielding materials against detrimental electromagnetic radiation plays an essential role. Meanwhile, the EMI shielding materials with high flexibility and functional integrity are highly demanded for emerging shielding applications. Hitherto, a variety of flexible EMI shielding materials with lightweight and multifunctionalities have been developed. In this review, we not only introduce the recent development of flexible EMI shielding materials, but also elaborate the EMI shielding mechanisms and the index for "green EMI shielding" performance. In addition, the construction strategies for sophisticated multifunctionalities of flexible shielding materials are summarized. Finally, we propose several possible research directions for flexible EMI shielding materials in near future, which could be inspirational to the fast-growing next-generation flexible electronic devices with reliable and multipurpose protections as offered by EMI shielding materials.
随着5G通信技术的快速发展，近年来电子设备的电磁干扰（EMI）屏蔽已成为迫切需求，其中开发相应的抗有害电磁辐射的EMI屏蔽材料起着至关重要的作用。同时，新兴的屏蔽应用对具有高柔韧性和功能完整性的EMI屏蔽材料有很高的要求。迄今为止，已经开发出了多种具有轻质和多功能特性的柔性EMI屏蔽材料。在这篇综述中，我们不仅介绍了柔性EMI屏蔽材料的最新进展，还阐述了EMI屏蔽机制以及“绿色EMI屏蔽”性能指标。此外，总结了柔性屏蔽材料复杂多功能性的构建策略。最后，我们提出了未来一段时间内柔性EMI屏蔽材料几个可能的研究方向，这可能会为快速发展的下一代柔性电子设备带来启发，这些设备可通过EMI屏蔽材料提供可靠且多功能的保护。
