摘要:
聚吡咯与石墨烯都具有良好的导电性,并易于与其他材料复合. 为了改善金属氧化物材料的电化学性能,采用两步法,先合成氧化石墨烯/聚吡咯复合物,利用高锰酸钾与乙二醇在微波下与氧化石墨烯/聚吡咯复合物反应,制备四氧化三锰/聚吡咯/还原氧化石墨(Mn3O4/PPy/rGO)复合材料,利用扫描电镜、傅立叶红外光谱和X射线衍射对Mn3O4/PPy/rGO复合材料的微观形貌及结构进行表征,并通过循环伏安法和计时电位法对其电化学性能进行测试. 结果表明,电流密度为0.5 A/g时,Mn3O4/PPy/rGO复合材料的电容达到546 F/g,经过800圈循环伏安测试后的电容保持率为94.8%. 表明Mn3O4/PPy/rGO复合材料具有良好的电化学可逆性与电化学稳定性. 其优良的电化学性能可能是Mn3O4/PPy/rGO复合材料中三种组分共同作用的结果,可望应用于新型超级电容器.
Abstract:
Polypyrrole and grahene are conducting materials with excellent compatibility with other materials. To improve the electrochemical property of metal oxide materials, manganic manganous oxide/polypyrole/ graphene (Mn3O4/PPy/rGO) ternary nanocomposites were prepared by two-step method. Scanning electron microscopy, Fourier infrared spectrum and X-ray diffraction techniques were carried out to characterize the microstructures and properties of the Mn3O4/PPy/rGO ternary nanocomposites. Moreover, the electrochemical performance was tested by cyclic voltammetry and chronopotentiometry. The result indicates that the specific capacitance of the ternary nanocomposites reaches 546 F/g at the current density of 5 A/g, which keeps 94.8% by 800 cyclic voltammetry tests. It indicates that Mn3O4/PPy/rGO ternary nanocomposites have good electrochemistry reversibility and recyclable properties. It suggests that the mutual interactions among the components of Mn3O4, PPy and rGO in the nanocomposite results in the electrochemical performance and these ternary nanocomposites could be used as super-capacitors in future.
