摘　　要：5G通信中电磁污染尤为严重,吸波材料可有效的吸收和衰减电磁波,将电磁能转换为热能的形式散失掉,已被广泛应用于航天航空、军事设施及电子通信等领域。然而,电子设备的小型化、集成化与高频化使电子设备无法及时将其产生的热能耗散掉,从而影响设备的正常运行。因此,如何将导热材料高效的应用于电磁波吸收成为了当前吸波领域研究的重点和热点。基于此,本文综述了不同种类的导热材料在电磁波吸收中的应用及研究进展,首先按照组成成分介绍了导热材料的种类,并详细阐述了金属材料、陶瓷材料、碳材料及其复合物和导热高分子材料及其复合物的导热机制及不同导热材料在电磁波吸收中的作用机制与应用。最后对导热吸波一体化材料未来的研究方向及推广应用提出了见解。Electromagnetic pollution is a significant concern in 5G communication.Electromagnetic wave absorb-ing materials can efficiently soak up and decrease the intensity of electromagnetic waves,whereby they dissipate the energy as heat.These materials have extensive applications in aerospace,military equipment and electronic communications.However,the miniaturization,integration and high frequency of electronic equipment make it impossible for electronic equipment to dissipate the heat energy generated by it in time,thus affecting the normal operation of the equipment.Therefore,how to efficiently apply thermally conductive materials to electromagnetic wave absorption has become the focus and hotspot of current research in the field of wave absorption.This paper reviews the application and research progress of different kinds of thermal conductive materials in electromagnetic wave absorption.Firstly,the types of thermal conductive materials are introduced according to the composition,and the thermal conduction mechanism of metal materials,ceramic materials,carbon materials and their compo-sites,thermal conductive polymer materials and their composites,as well as the mechanism and application of different thermal conductive materials in electromagnetic wave absorption are described in detail.Finally,the future research direction and application of integrated materials for thermal conductivity and electromagnetic waveabsorptionareputforward.
