二茂铁高分子Schiff碱-Mn吸波剂的研究

Study on ferrocene polymeric Schiff-base-Mn absorbent

用分子设计和性能剪裁新思路,将3种有机基团（间苯二胺、吡啶二胺、萘二胺）引入二茂铁高分子金属配合物磁体中,合成既含＂磁性＂基元又有＂半导体＂基元的二茂铁高分子Schiff碱-Mn磁性半导体吸波剂,研究了2~12GHz广泛频段取代基与电磁参数和吸波性能的关系。并首次报道用Nd/YAG激光器发射的紫外激光（波长335.0nm）对吸波剂进行了激光照射,研究表明,激光照射30min,吸波剂的微波吸收达最大值,吸收频带也较宽。例如,取代基为萘二胺的吸波剂（FcsⅢ-Mn）,最好的反射率达-17.0dB,带宽6.5GHz,为研发新一代高性能吸波材料提供一种有效而简便的方法。

Three substitutents（m-phenylenediamine,1,4-Pyridyldiamine and 1,8-naphthyldiamine）were introduced into ferrocene polymeric magnetic coordination compounds.The ferrocene polymeric Schiff-base-Mn absorbent with ＂magnetic group＂and＂semi-conductive group＂was synthesized on the basis of molecular design and functional design thinking.That the relation of substitutents,electromagnetic parameters and absorbing properties were studied under 2-12 GHz.It was first report that the absorbents were irradiated by laser ultraviolet beam of Nd/YAG（wave length 355.0nm）.The results showed that the microwave absorbing was largest value and frequency was wide after irradiation 30 min.For example,the naphthyldiamine group-contaning absorbent（FcsIII-Mn）had the reflectivity up to-17.0dB and its frequency width was6.5GHz.A effective and simple method for studing a new generation of high performance wave-absorbing material was provided.
