| 题目: | Mechanical Properties of Locally Oxidized Graphene Electrodes | | | | | 作者: | Fei Hui, Yuanyuan Shi, Yanfeng Ji, Mario Lanza & Huiling Duan | | | | | 单位: | Institute of Functional Nano and Soft Materials, Soochow University, 199 Ren-Ai Road, Suzhou, Industrial Park,Suzhou, 215123 Jiangsu, China State Key Laboratory for Turbulence and Complex System, CAPT, Department of Mechanics and Engineering Science College of Engineering, Peking University, Beijing 100871, China | | | | | 摘要: | Graphene has many outstanding mechanical, electronic and optical properties, which makes it an ideal material for future transparent-flexible electronic devices. In such applications, graphene is exposed to atmospheric conditions and must withstand high mechanical stresses without forming cracks or discontinuities, so that the electrical current can flow along it. Although graphene is a very resistant material, local oxidation of graphene may alter its pristine structure, leading to a lower mechanical strength and high risk of fracture. Here, we analyze the mechanical properties of graphene in oxidative environments using a wide range of nanoscale tools and performing accelerated oxidation tests. Our experiments indicate that local oxidation of graphene sheets may alter its mechanical properties, leading to soft locations that easier to indent and increase the frictional coefficient of the sheets. | | | | | 影响因子: | 1.438 | | | | | 分区情况: | 2区 | | | | | 链接: | http://link.springer.com/article/10.1007/s00419-014-0957-4 |
