辐照对高分子磁体/M型铁氧体复合物电磁性能的影响

Influence of irradiation on the electromagnetic properties of ferrocene polymer magnet/M type ferrite composites

报道了在60Coγ辐照下二茂铁高分子磁体/M型六角晶系铁氧体复合物(简称OPM/M型)辐照剂量、组分配比、温度对复合物电磁参数的影响,并用IR差示光谱、SEM(电子扫描显微镜)研究了辐照剂量对复合物的降解与交联之影响。研究表明,适当的辐照剂量及组分配比可控制复合物的电磁参数,并有可能获得一种用于0.1-12GHz下的轻质和良好吸波特性的新型吸波剂。

In this paper, we present a study on effects of irradiation dose, content and femperature on electromagnetic properties of ferrocene polymer magnet/M type ferrite composites (i.e. OPM/M). Cross-linking and degradation of the materials in their composites were studied by IR differential spectrometry and SEM. The results show that electromagnetic parameters of the materials can be controlled by irradiation dose arid content of the composites. It is possible that a new type absorbent of lower density and good absorbing properties will be prepared and used for 0.1 to 12GHz.
