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。
With the new ideas of molecular design and performance tailoring, three kinds of organic groups (m-phenylenediamine, pyridinediamine and naphthalenediamine) were introduced into the ferrocene polymer metal complex magnet to synthesize both “magnetic” And the “semiconductor ” element of the ferrocene polymer Schiff base-Mn magnetic semiconductor absorber, a wide range of 2 ~ 12GHz substituents with electromagnetic parameters and the relationship between absorbing properties. The laser irradiation with UV laser (wavelength 335.0nm) was reported for the first time using Nd / YAG laser. The results show that the microwave absorption reaches the maximum and the absorption band is also wide when the laser is irradiated for 30min. For example, the substituent of naphthalene diamine absorbing agent (FcsⅢ-Mn), the best reflectance of -17.0dB, bandwidth 6.5GHz, for the development of a new generation of high-performance absorbing material provides an effective and easy way.
