摘要: 随着5G网络的兴起，电磁辐射和干扰问题日益凸显，因此开发有效的电磁屏蔽材料尤为迫切。相较于传统金属基电磁屏蔽材料的高成本、高密度、难加工、易腐蚀等诸多限制，聚合物基电磁屏蔽复合材料具有低密度、耐腐蚀、易加工等优异的特性而备受关注。构建隔离结构、多孔结构、分层结构等异质结构，能够诱导导电填料的取向分布，使聚合物基电磁屏蔽复合材料在低填料含量下，获得高效的导电网络和优异的导电性能，从而提高其屏蔽性能。据此，本文综述了目前具有异质结构的聚合物基电磁屏蔽复合材料的研究进展，重点介绍了异质结构构建策略、制备技术及其对电磁屏蔽性能的影响，最后对具有异质结构的聚合物基电磁屏蔽复合材料的未来发展提出了展望。本工作对于提升聚合物基电磁屏蔽复合材料性能及其在通信、智能穿戴、航空航天等领域应用的开拓都具备指导意义。Abstract: With the rise of 5G networks, electromagnetic radiation and interference issues are becoming increasingly prominent, so the development of effective electromagnetic shielding materials is particularly urgent. Compared with the high cost, high density, difficult processing, easy corrosion and many other limitations of traditional metal-based electromagnetic shielding materials, polymer-based electromagnetic shielding composites have attracted much attention due to their excellent properties such as low density, corrosion resistance and easy processing. The construction of heterogeneous structures such as isolation structure, porous structure and layered structure can induce the orientation distribution of conductive fillers, so that polymer-based electromagnetic shielding composites can obtain excellent conductivity at low filler content, thereby improving their shielding performance. Based on this, this paper reviews the current research progress of polymer-based electromagnetic shielding composites with heterogeneous structures, focusing on the construction strategy and preparation technology of heterogeneous structures and their influence on electromagnetic shielding performance. Finally, prospects for the future development of polymer-based electromagnetic shielding composites with heterogeneous structures are proposed. This work has guiding significance for improving the performance of polymer-based electromagnetic shielding composites and the development of their applications in communications, smart wearables, aerospace and other fields.
