摘要
目的介电损耗低、吸收带宽较窄、密度高等缺点制约着羰基铁粉(Carbonyl Iron Powder,CIP)在吸波领域中的应用。在CIP材料的基础上,使用不同的改性方法,开发“轻、宽、强、薄”的CIP微波吸收材料,实现对微波的高效吸收。方法综述近年来羰基铁粉作为吸波材料的研究现状,介绍和分析不同改性方法,如形貌改性、涂覆改性、复合改性等对羰基铁复合材料吸波性能的影响。结论CIP作为微波吸收材料,可以通过不同改性方法来改善缺点,制备的复合材料更符合当下社会对吸波材料的需求,与传统CIP材料相比,CIP复合材料作为微波吸收剂,具有更大的潜力。
The application of carbonyl iron powder(CIP)in wave absorption is restricted by its low dielectric loss,narrow absorption bandwidth,high density,and other shortcomings.The work aims to develop"light,wide,strong,thin"CIP microwave absorbing materials through different modification methods based on CIP materials,to effectively absorb microwaves.The research status of using carbonyl iron powder as wave absorbing materials in recent years was reviewed.The effects of different modification methods,such as morphology modification,coating modification and composite modification,on the wave absorbing properties of carbonyl iron composites were introduced and analyzed.As a microwave absorbing material,CIP can be improved by different modification methods to ameliorate the shortcomings.The prepared composites are more in line with the current demand for wave absorbing materials.Compared with traditional CIP materials,CIP composites have greater potential as microwave absorbers.
