Electrochemical Performances of Layered Polypyrrole/Chemically Reduced Graphene Oxide Nanocomposites as Supercapacitor Electrodes
摘要
Abstract
Nanocomposites of polypyrrole （Ppy） and chemically reduced graphene oxide （ CRGO）, Ppy/ CRGO, have been fabricated through in-situ polymerization of pyrrole on graphene oxide （GO） sheets. The as-synthesized Ppy/CRGO composites were characterized complementarily using scanning electron microscopy （SEM）, tbermogravimetric analysis （TGA） and Fourier transformed infrared spectroscopy （FT-IR）. By control- ling the initial ratio of the GO to pyrrole, the layered composites could be obtained and their thickness could be tuned properly. The Ppy/CRGO electrodes were prepared using a mechanical compressing technique and their elec- trical conductivity and electrochemical properties were characterized systematically. We demonstrated that as elec-trodes for supercapacitor, the Ppy/CRGO composites with Ppy to CRGO mass ratio of 10：1 showed a competitive capacitance of 421F· g^ -1 that could be further increased to 509 F· g^ -1 by introducing pores in it, which is higher than that of Ppy alone. Given the manifest electrical and electrochemical properties, we envisage that the Ppy/ CRGO composites should find applications in supereapacitors.关键词
