中文摘要	In this study, a simple and controllable two-step electrochemical process is described for the synthesis of graphene sheets (GS) ﬁlm on a cleaned indium tin oxide (ITO) sheet electrode. Namely, the main procedures involve the electrophoretic deposition (EPD) of graphene oxide (GO) ﬁlm onto ITO electrode and the subsequent in situ electrochemical reduction (ECR) of GO to generate GS ﬁlm. X-ray photoelectron spectroscopy (XPS) measurement demonstrates that most of the oxygen-containing functional groups in GO ﬁlm have been removed after ECR. By electrochemical measurements, the maximum speciﬁc capacitance of the prepared GS ﬁlm electrode was calcu- lated to be 156 F g-1 , besides, the capacitance retention of the material remained 78% after 400 times of cycling, showing a promising prospect as supercapacitor materials.
