摘　　要：石墨烯具有独特的二维纳米结构、高比表面积和优异的电化学性能,而且变形后仍保持器件的原始性能。分析了石墨烯柔性超级电容器的工作原理,研究了以石墨烯为电极材料的柔性超级电容器的变形特性,其变形类型可由小角度弯曲、卷曲和拉伸扩展至任意静态变形,甚至动态变形。最后对石墨烯柔性电容器在便携式电子器件中的应用进行了展望。Graphene is a typical two-dimensional monatomic-layered material and has high theoretical electrochemical capacitance. The working mechanism of graphene supercapacitors is investigated. The deformation properties of flexible supercapacitors based on graphene electrodes are studied. The type of deformations can be extended from static bending curl and stretching to arbitrary even dynamic deformation. Finally, the application prospect of flexible graphene supercapacitors is envisioned in portable electronics.
