摘　　要：近年来,石墨烯因其优异的电学和光学等特性,越来越受到人们的广泛关注。研究人员应用多种方法来合成石墨烯并且探讨其潜在的应用价值。本文首先简要介绍了石墨烯的结构及其基本的物理性质,并简单回顾了石墨烯的合成方法和表征手段。在此基础上,讨论了石墨烯/银复合薄膜在透明导电膜中的应用,并详细介绍了我们在该领域的研究成果。用化学气相沉积法(CVD)和多羟基法分别制备了双层石墨烯及银纳米线,成功合成了石墨烯/银复合薄膜,结果表明复合薄膜的方块电阻可降低至26Ω?□^(-1),展示了其在光电器件上广泛的应用前景。Over the past decade, graphene has been the focus of intensive research because of its remarkable physical and chemical properties. Researchers have made many efforts to synthesize graphene and investigate its potential applications. In this article, we first briefly review the fabrication processes and properties of graphene. Then, we discuss the application of graphene/Ag hybrid films as transparent conductive films （TCFs）. Next, we introduce our results on this topic. Graphene and Ag nanowires were synthesized by chemical vapor deposition （CVD） and the polyol process, respectively. We successfully fabricated a graphene/Ag hybrid film with a low sheet resistance （Rs） of 26Ω·□^-1. Finally, we describe the main challenges facing graphene hybrid films and their potential applications in a wide range of optoelectronic devices.
