▎ 摘  要

A novel nanoplatelet-like structure of the composites of polypyrrole (PPy) and graphene (GR) is facilely synthesized by an electrochemical method and is further employed as a supercapacitor. The nanocomposite of PPy/GR shows a porous structure with a specific surface area of as high as 136.5 m(2) g(-1). As a result, the composite material exhibits a high specific capacitance of 285 F g(-1) at a discharge rate of 0.5 A g(-1), and excellent cycling stability. Specifically, over 90% of its initial capacitance can be retained after 1000 charge/discharge cycles. With advantageous features, such as facile fabrication process, high specific capacitance and excellent cycle life, this electrochemically synthesized PPy/GR nanocomposite is quite promising for high-performance supercapacitor applications.
