论文通过将吡咯单体在低温下与氧化石墨烯进行原位聚合，获得聚吡咯/石墨烯（Ppy/CRGO）复合材料. 采用场发射电子显微镜（FESEM）、红外 (FT-IR)和热重 (TGA)对复合物的表面形貌、结构进行表征. FESEM结果表明，通过控制氧化石墨烯（GO）和吡咯单体的质量比例，可以对复合物的层状和厚度进行调控. FT-IR和TGA结果表明聚吡咯（Ppy）是通过化学键合的方式与氧化石墨烯复合在一起。通过机械冷压法将粉末状Ppy/CRGO复合物压成圆片电极，并探讨了石墨烯和聚吡咯复合比例、反应时间、烘干温度、孔隙率等因素对Ppy/CRGO复合物电极的电学和电化学性能的影响. 结果表明，Ppy与CRGO质量比为10:1所制得的Ppy/CRGO复合物的电容量为421 F?g-1，通过在电极中引入孔隙，电容量能进一步提升为509 F?g-1.

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), thermogravimetric analysis (TGA), and Fourier transformed infrared spectroscopy (FT-IR). By controlling 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 electrical conductivity and electrochemical properties were characterized systematically. We demonstrated that as electrodes for supercapacitor, the Ppy/CRGO composites with Ppy to CRGO ratio of 10:1 showed a competitive capacitance of 421 F?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 supercapacitors.
