▎ 摘　　要

Due to its special monolayer structure, graphene has interesting physical and chemical properties. Over the past ten years, graphene studies have has produced great effects on physics, chemistry, and material science and engineering, and have become one of the high-profile international frontiers and research focuses. The controllable preparation, assembly and functional applications of graphenes are essential for graphene studies. In recent years, researchers are constantly exploring the new ways for preparation and application of graphenes and their functional composites. Among them, the composite of graphene and conductive polymer polypyrrole (PPy) has attracted much attention in particular, and a series of valuable insight into the new graphene/polymer composites has been achieved. In this report, the recent important advances in controllable synthesis of graphene/PPy composites are summarized and some of the new developments in the field of electrochemical applications, including catalysis, actuator, supercapacitors, sensors, and so on, are discussed.
