| 摘要: 在壳聚糖的作用下，采用简单的一步法合成了具有星状结构的氯化银/聚苯胺核壳型复合材料。当壳聚糖的浓度为1%时，所制备的氯化银/聚苯胺复合材料具有高度的分散性，壳层厚度为30～80 nm、核的直径在25～60 nm范围内。通过透射电镜、红外光谱和X-射线衍射对样品的形态和组成进行了表征。循环伏安实验结果表明这种复合材料在中性条件下具有很好的电化学活性。 |

| Abstract: Silver chloride@polyaniline (PANI) core-shell composites with a star-like structure were synthesized through a facile one-step process in the presence of chitosan. When the chitosan concentration was 1%， highly dispersed AgCl@PANI core-shell nanostructure with a shell thickness of 30～80 nm and a core diameter of 25～60 nm could be obtained. The morphology and composition were characterized by transmission electron microscopy (TEM)， Fourier transform infrared (FTIR) and X-ray diffraction (XRD). Cyclic voltammetric experiments indicated that this kind of material showed excellent electrochemical activity in neutral pH environment. |
