 | Highly flexible and shape-persistent graphene microtube and its energy storage performance Original Research Article Carbon, Available online 15 October 2017, Pages Junjie Yang, Wei Weng, Yang Zhang, Xiaowen Du, Yunxia Liang, Lijun Yang, Xiaogang Luo, Yanhua Cheng, Meifang Zhu
Graphical abstractGraphene microtube was fabricated by a novelelectrochemical method. A high quality is achieved by an effective reduction of GO to graphene and a high regularity of layered framework of graphene sheets in the tube wall. Therefore the resulting graphene microtube presents excellent flexibility and electrochemical performance.Image 1
 | Enhanced thermal conductivity of graphene/polyimide hybrid film via a novel "molecular welding" strategy Original Research Article Carbon, Available online 15 October 2017, Pages Haoliang Li, Sichang Dai, Jie Miao, Xian Wu, Navya Chandrasekharan, Hanxun Qiu, Junhe Yang
Graphical abstractA novel "molecular welding" strategy was proposed to fabricate a flexible, ultrathin, but highly conductive graphene/polyimide (g-GO/PI) hybrid films. An enhancement of 21.9% in the in-plane thermal conductivity was achieved compared to the pristine graphene film. PI was applied as a solder to weld up the micron-sized graphene platelets through the covalent bonding. This is believed as the key to the considerable enhancement of the in-plane thermal conductivity of g-GO/PI hybrid films. Such a "molecular welding" conception provides a promising way to deliver the next-generation graphene-based film for thermal management.Image 1
