二茂铁高分子磁性吸波剂的结构与电磁性能研究

Studies on structure and electromagnetic properties of ferrocenyl polymeric magnetic absorbent

合成了二茂铁酰腙型金属（Mn、Fe、Co）配位的高分子吸波剂（OPA-M）,研究表明,OPA-M取代基为共轭体系较大的联苯基,配位金属为Mn时,它的最大的反射衰减量（R）为-15dB（6.9GHz）,R〉-10dB的频宽4.2GHz（5.8-10.0GHz）。另外,OPA-Mn含3%炭纤维的复合吸波材料最大反射衰减量为-18dB（8.5GHz）,R〉-10dB的频宽为6.0GHz（5.5-11.5GHz）,而密度仅2.2g/cm3,因此,这种新一代高分子磁性吸波剂在理论研究和军工应用有重要价值。

The ferrocenyl acylhydrazone type coordinated metal polymeric absorbent （OPA-M） was synthesized. It was shown that its the largest reflective loss（R） is --15dB（6.9GHz） and the frequency wide is 4.2GHz（5.8- 10GHz,R〉-10dB）, when the substitutent is biphenyl growp and the coordinated metal is manganese in OPA- M. On the other hand, the largest reflective loss is --18dB （8.5GHz） and its frequency wide is 6.0GHz （5.5- 11.5GHz, R 〉-10dB） of the OPA-M composited absorbent with 3%carbon fiber, but their specific gravity is only 2.2. However, the new-generation polymeric magnetic absorbent will have important value in theory and military industry.
