Polypyrrole (PPy)-coated Ag nanoparticles and nanowires were fabricated through the redox reaction between pyrrole monomer and silver nitrate in the presence of chitosan. The morphologies, compositions, and electrochemical activities of PPy/Ag composites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy, and Cyclic voltammetry. The synthetic route employed here is simple and inexpensive and can be extended to prepare other conducting polymer/inorganic nanocomposites.
在壳聚糖存在的情况下，通过吡咯单体与硝酸银之间的氧化还原反应制备了聚吡咯（PPy）包覆的银纳米颗粒和纳米线。采用扫描电子显微镜、透射电子显微镜、X射线衍射、热重分析、傅里叶变换红外光谱和循环伏安法对PPy/Ag复合材料的形貌、组成和电化学活性进行了表征。这里采用的合成路线简单且成本低廉，并且可以扩展用于制备其他导电聚合物/无机纳米复合材料。
