【摘要】 制备了两种磁性材料与聚苯胺合成的复合物,采用3cm波导式测量线在8～14GHz频率范围内,用多点拟合的实验和计算方法对这类复合聚苯胺的电磁参数及微波吸收特性参数进行了测量.实验结果表明,复合聚苯胺在吸收剂中的浓度对电磁参数及吸波性能的影响很大.对Mn-Zn铁氧体复合聚苯胺,当浓度为0.23g/cm3时,其平均衰减为14.767dB,最大衰减为40.260dB,衰减为10dB时的频宽可达3.6GHz,是一种性能优良的微波吸收材料.更多还原

【Abstract】 <Abstrcat> A procedure for synthesizing polyaniline with inorganomagnetic material and aniline is presented. The measured results of electromagnetic parameters and absorbing properties are given. It is shown that the concentration of magnetic and conductive polyaniline influences significantly the electromagnetic parameters and absorbing properties of microwave absorbent. In particular, a polyaniline doped by Mn-Zn ferrities is synthesized. It shows good microwave absorption with 14.767 dB average attenuation in the range of 8~14 GHz and 40.260 dB peak value.更多还原
