随着电子设备的发展和复杂化，电磁干扰和污染问题日益严重，对人类健康和设备运行造成潜在威胁。基于常用金属及其合金基电磁屏蔽材料因密度大、易腐蚀且屏蔽机制单一，难以满足现代前沿领域对轻量化和柔韧性的要求。相比之下，碳基纳米复合材料和柔性磁损耗材料等因密度小、导电性好、耐腐蚀和柔韧性佳等优势，成为电磁屏蔽领域的研究热点。通过复合材料设计与结构优化，可赋予屏蔽材料以柔性，实现其在复杂形变环境下的高效屏蔽效能。综述了柔性电磁屏蔽材料的研究进展，重点分析了材料种类、屏蔽结构和制备方法。最后，结合可穿戴电子设备、航空航天和医疗领域的应用实例，展示了其广阔前景。
Abstract：With the development and complexity of electronic equipment, electromagnetic interference and pollution has become serious problems, posing a potential threat to human health and equipment operation. Conventional metal-based and their alloy based electromagnetic shielding materials are difficult to meet requirements for lightweight and flexibility in morden frontier fields due to high density, easy corrosion and single shielding mechanism. In contrast, carbon-based nanomaterial composites and flexible magnetic loss materials have become research hotspots in the field of electromagnetic shielding due to the advantages of low density, good conductivity, corrosion resistance and good flexibility. Shielding materials can be endowed with flexibility, enabling them to achieve high-efficiency shielding performance in complex deformation environments through composite design and structure optimization. The research progresses of flexible electromagnetic shielding materials are reviewed, focusing on the analysis of material types, shielding structure and preparation methods. Finally, broad prospects are proposed by combining the applications in wearable electronic devices, aerospace and medical fields.
