摘要: 采用水热法制备尖晶石结构的Co0.5Zn0.5Fe2O4纳米颗粒,再采用原位聚合法制备Co0.5Zn0.5Fe2O4/聚苯胺(PANI)复合物,对其结构及电磁性能进行了表征. 结果表明,复合物中Co0.5Zn0.5Fe2O4与PANI之间存在键的作用;在频率2~18 GHz范围内,与纯Co0.5Zn0.5Fe2O4相比,复合物的介电常数实部与虚部均增大,磁导率的实部与虚部均减小;复合物的最大吸收峰比纯Co0.5Zn0.5Fe2O4明显提高,最大吸收峰在频率11~13 GHz范围内约为15 dB.

Abstract: Spinel structured Co0.5Zn0.5Fe2O4 nano-particles were prepared by hydrothermal method, and different ratios of Co0.5Zn0.5Fe2O4 and polyaniline (PANI) composites were prepared by in-situ polymerization method. The composites were characterized. The results showed that there was the bond reaction between Co0.5Zn0.5Fe2O4 and PANI in the composites. In the frequency range of 2~18 GHz, compared with pure Co0.5Zn0.5Fe2O4, both the real and imaginary parts of dielectric constant of Co0.5Zn0.5Fe2O4/PANI composites increased, while both the real and imaginary parts of the permeability of them decreased. The maximum absorption peaks of composites were improved obviously, compared with the pure Co0.5Zn0.5Fe2O4, and their maximum absorption peaks were both about 15 dB in the frequency range of 11~13 GHz.

Key words: Co0.5Zn0.5Fe2O4/PANI, in-situ polymerization, composite, electromagnetic property
