在水溶液中采用一步法在聚吡咯纳米球表面负载二氧化锰纳米片,得到聚吡咯/二氧化锰复合材料,运用透射电子显微镜、傅里叶红外光谱和X射线衍射对其形貌和结构进行表征,并对其电化学性能进行研究.结果表明,所制备的复合材料具有理想的电化学性能,在超级电容器领域有很大的发展潜力.%Polypyrrole(PPY)/MnO2 composites have been synthesized in the solution by one step method for MnO2 nanosheets on surfaces of PPY nanospheres. The morphology and structure of PPY/MnO2 composites were characterized by means of transmission electron microscope,fourier transform infrared spectroscopy and X-ray diffraction. In addition,the electrochemical performance was studied. The results show that PPY/MnO2 composites have excellent electrochemical properties,which evidence their potential appli-cation as supercapacitors.
