| 摘 要： | 对近年来关于聚合物基电磁屏蔽材料的报道进行了综述。重点总结分析了不同结构(如多孔结构、隔离结构和分层结构)及其他特殊结构聚合物基电磁屏蔽材料的屏蔽效能和屏蔽机制。与均匀分布聚合物基复合材料相比，通过结构设计使填料富集，再取向并连通从而形成高效导电网络，不仅能减少填料用量，且能有效提高复合材料的电磁屏蔽性能。最后，提出了聚合物基电磁屏蔽材料的未来发展方向。

| Abstract: | This review introduces the recent reports on polymer-based electromagnetic shielding materials. The shielding mechanism and shielding effectiveness of polymer-based electromagnetic shielding materials with different structures (porous structure, segregated structure and layered structure) and other special structures are summarized and analyzed emphatically. Compared with the composite materials with uniformly distributed fillers in the polymer matrix, the structure design can enrich, re-orient and connect the fillers to form efficient conductive networks, which can not only reduce the amount of fillers, but also improve the electromagnetic shielding performance of the composites. Finally, this review put forward the development direction of polymer-based electromagnetic shielding materials in the future. |
