摘　　要：微波吸收材料的研究和应用对于减少电磁污染和实现军事装备隐身具有重要意义。其中,铁磁吸波材料具有优越的磁性能、较高的Snoek截止频率、饱和磁化强度和居里温度,表现出优异的电磁波损耗能力,是一种很有前景的吸波材料。然而,铁磁颗粒具有阻抗匹配差、易氧化、密度高、趋肤效应强、温度稳定性差等缺点,通过微观形貌调控等方式与碳基材料、导电金属、导电聚合物、半导体等材料复配,可以有效改善铁磁吸波材料的性能。本文总结了几种铁基复合材料的制备方法、性能和作用机制等,并展望了未来的研究方向。The research and application of microwave absorbing materials is of great significance for reducing electromagnetic pollution and realizing the stealth of military equipment.Among them,ferromagnetic microwave absorbing materials have superior magnetic properties,high Snoek cut-off frequency,saturation magnetization and Curie temperature,and exhibit excellent electromagnetic wave loss ability,which is a promising microwave absorbing material.However,ferromagnetic particles have disadvantages such as poor impedance matching,easy oxidation,high density,strong skin effect,and poor temperature stability.By compounding with carbon-based materials,conductive metals,conductive polymers,semiconductors and other materials,the performance of ferromagnetic microwave microwave absorption materials can be effectively improved.In this review,the preparation methods,properties and action mechanisms of several iron-based composites are reviewed,and the future research trends are prospected.
