摘要
用丙烯酸对二茂铁型高分子磁体 (以下简称高分子磁体 )进行改性 ,研究了高频微波下改性高分子磁体的频率—磁导率—磁损耗 (f μ′ μ″)及频率—介电常数—介电损耗 (f ε′ ε″)的关系 .研究结果表明 :丙烯酸改性的高分子磁体具有较高的介电常数 (ε′)、较低的介电损耗 (ε″)和磁损耗 (μ″) ,这对电子器件的小型化有重要价值 .
In this paper, we have reported the ferrocene type polymeric magnet modified by acrylic acid, the relation between frequency magnetic conductivity magnetic loss (f μ′ μ″) and frequency dielectric constant dielectric loss (f ε′ ε″) of the modified polymeric magnet which has been studied at high frequency and microwave band. Results show that it has higher dielectric constant (ε′) , lower dielectric loss ( ε ″) and magnetic loss ( μ ″). It is very important for small volume of devices.
