【摘要】:用分子設(shè)計(jì)和性能剪裁新思路,將3種有機(jī)基團(tuán)(間苯二胺、吡啶二胺、萘二胺)引入二茂鐵高分子金屬配合物磁體中,合成既含"磁性"基元又有"半導(dǎo)體"基元的二茂鐵高分子Schiff堿-Mn磁性半導(dǎo)體吸波劑,研究了2~12GHz廣泛頻段取代基與電磁參數(shù)和吸波性能的關(guān)系。并首次報(bào)道用Nd/YAG激光器發(fā)射的紫外激光(波長(zhǎng)335.0nm)對(duì)吸波劑進(jìn)行了激光照射,研究表明,激光照射30min,吸波劑的微波吸收達(dá)最大值,吸收頻帶也較寬。例如,取代基為萘二胺的吸波劑(FcsⅢ-Mn),最好的反射率達(dá)-17.0dB,帶寬6.5GHz,為研發(fā)新一代高性能吸波材料提供一種有效而簡(jiǎn)便的方法。
[Abstract]:Three organic groups (resorcinenediamine, pyridine diamine, naphthalene diamine) were introduced into ferrocene polymer metal complex magnets with new ideas of molecular design and performance tailoring. A ferrocene polymer Schiff base mn magnetic semiconductor absorbent containing both magnetic and semiconductor elements has been synthesized. The relationship between the electromagnetic parameters and the absorbing properties of the substituents in the wide frequency range of 21GHz has been studied. It is reported for the first time that the ultraviolet laser (wavelength 335.0nm) emitted by ND / YAG laser is used to irradiate the absorbent. The results show that the microwave absorption of the absorber reaches the maximum and the absorption band is wider when the laser is irradiated for 30 min. For example, the absorbent (FCS 鈪,
