| 中文摘要: |
| 近年来，随着军事隐身技术及电磁污染防治的需要，吸波材料的研究引起了越来越多的关注。传统的吸波材料，如铁氧体、金属微粉、碳材料及导电聚合物等，难以满足“薄、宽、轻、强”的综合要求，磁性粉体包覆式核壳型复合吸波材料可同时具备核层和壳层材料的性能，能表现出优异于单组分材料的良好吸波能力，近年来成为研究的热点。首先阐述了核壳结构磁性复合吸收剂的结构形式，重点综述了近年来有关磁性粉体包覆式核壳型复合吸波材料的研究成果，并进行了归纳、评述，将磁性粉体包覆式核壳型复合吸波材料分为两大类—磁-磁复合核壳型吸收剂及电-磁复合核壳型吸收剂。在此基础上，结合课题组近年来研究成果，论述了羰基铁包覆式核壳型吸收剂。最后指出了磁性粉体包覆式核壳型复合吸波材料未来研究亟待解决的问题和发展方向。 |

| Nowadays, more and more researchers pay attention to the microwave absorbing materials along with the devel-opment of stealth technology for military platforms and the requirements of electromagnetic pollution control. Traditional mi-crowave absorbers, such as ferrite, metal powder, conductive magnetic fibers, carbon materials, conducting polymers, etc. cannot meet the comprehensive requirements of “thinness, width, lightness and strength”. Core shell structured magnetic composite wave absorbing materials can simultaneously exhibit the properties of core and shell material and show more excellent absorbing ability than single component material. In recent years, it has become a hot spot of research. The structure of core shell structured magnetic composite wave absorbing materials was described firstly, and then the research achievements of core shell structured magnetic composite wave absorbing materials were summarized and reviewed. The magnetic powder coated core shell composite absorbing materials were divided into two magnetic composite core shell type magnetic absorbents and the magnetic absorbent materials. On this basis and according to the results of research group in recent years, carbonyl iron coated core shell absorbers were discussed. Finally, the problems and development directions of magnetic powder coated core shell composite absorbing materials in the future were pointed out. |
