【摘要】 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。更多还原

【Abstract】 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.更多还原
