Composites of cobalt ferrite nanorods in a polyaniline matrix have been synthesized and characterized by electron microscopy observation, X‐ray diffraction, infrared spectroscopy, thermogravimetric analysis, electrical conductivity, and DC magnetization measurements. The composites were prepared using dodecylbenzenesulphonic acid both as a particle protector and as acid media. In the magnetic experiments, hysteresis loops were observed, revealing ferromagnetism for both particles and composites. The results indicate that the magnetic properties of the particles were preserved in the composites, and on the other hand, the conductivity was almost independent on the polymer/particle ratio. These composites are new materials that show easily tunable magnetic properties, and are expected to be candidates for applications such as microwave shields. POLYM. ENG.

聚苯胺基质中钴铁氧体纳米棒的磁性和导电复合材料

合成了聚苯胺基体中钴铁氧体纳米棒的复合材料，并通过电子显微镜观察，X射线衍射，红外光谱，热重分析，电导率和直流磁化强度进行了表征。使用十二烷基苯磺酸作为颗粒保护剂和酸介质制备复合材料。在磁性实验中，观察到磁滞回线，揭示了颗粒和复合材料的铁磁性。结果表明，复合材料中保留了颗粒的磁性，另一方面，电导率几乎与聚合物/颗粒比无关。这些复合材料是具有易于调节的磁性能的新材料，有望成为微波屏蔽等应用的候选材料。POLYM。ENG。SCI。，60：597–606，2020.©2020塑料工程师协会
