聚吡咯/还原氧化石墨烯复合物的合成及电容性能
Synthesis of Polypyrrole/Reduced Graphene Oxide and Its Capacitive Properties
摘要
Abstract
Polypyrrole/graphite oxide composites(PPy/GO) with different mass ratios were first prepared by in situ polymerization and then reduced by NaBH4 to form polypyrrole/reduced graphene oxide (PPy/RGO). The morphology and structure of the composites were characterized by X-ray diffraction ( XRD), Fourier transform infrared spectroscopy ( FT-IR ) and field emission scanning electron microscopy ( FESEM ). The electrochemical performances of the composites were investigated by cyclic voltammetry, galvanostatic charge discharge and electrochemical impedance techniques. The experimental results showed that the composites with the mass ratio of Py to GO up to 95 : 5 reached the specific capacitances of 401. 5 and 314. 5 F/g before and after reduction at the current density of 0. 5 A/g, respectively, which were much higher in comparison with pristine GO(34. 8 F/g) and PPy(267. 5 F/g). The capacitance retention is about 62. 5% for PPy/RGO after 1200 cycles, which is much better than those of 16. 8% for PPy and 46.4% for PPy/GO, indicating that the PPy/RGO has a high cycle stability and potential as electrode material for supercapacitors.关键词
