摘　　要：　用水热法制备了具有填充型Skutterudite结构的NaFe4P12单晶微米棒及纳米棒。采用乳液聚合法边聚合边复合制备了NaFe4P12-聚苯胺复合热电材料。用红外光谱、紫外光谱和X射线粉末衍射对材料进行了表征。用透射电镜研究了聚苯胺的形态和在棒状NaFe4P12材料表面聚合生长状态。首次观察到聚苯胺在NaFe4P12棒上的聚合及规律生长的"毛刷"结构。　　这种"毛刷"结构的发现将有助于对其复合机理的研究;这种结构有可能用于特殊用途的电子器件。Sodium filled skutterudite NaFe4P4 whiskers and nanowires were prepared by a hydrothermal synthesis method. Skutterudite-polyaniline thermoelectric composite was prepared by in situ compounding using an emulsion polymerization method. The nanowires and whiskers as well as the composites were characterized by infrared spectra UV/VIs spectra and X-ray diffraction. Transmission electron microscope observation on the composite was carried out to investigate the morphology and growth mechanism of polyaniline on the surface of the skutterudite wires. Polyaniline can be compounded on the surface of the wires. In some samples, polyaniline grows as a brush structure on the surface of the NaFe4P4 whisker.
