1石墨烯导热材料研究进展显示文摘石墨烯作为一种具有超高热导率的二维纳米材料,在导热领域有着广阔的应用前景。本文综述了石墨烯导热材料的研究进展,介绍了石墨烯本征热导率及其层数、缺陷、边缘情况等对热导率的影响,分析了石墨烯纤维的研究现状及存在的问题,讨论了各类石墨烯导热薄膜(纯石墨烯薄膜/石墨烯杂化薄膜/石墨烯聚合物复合薄膜)热导率的影响因素,归纳总结了各类三维石墨烯导热材料(无规分散石墨烯三维复合材料和特定结构石墨烯三维复合材料)的结构、性能与研究现状,最后指出了目前几种导热材料研究存在的问题并展望了石墨烯未来导热领域的发展方向,尤其是在LED照明、智能手机等高功率、高度集成系统中,石墨烯导热材料有着良好的发展前景。李岳 李炯利 朱巧思 梁佳丰 郭建强 王旭东 2021材料工程2021,49,11:12
2退火温度对柔性石墨烯薄膜力学性能的影响(英文)显示文摘通过抽滤法制备出氧化石墨烯薄膜,然后分别将其在1 300、1 400、1 500、1 600、1 700℃下进行炭化得到石墨烯薄膜。石墨烯薄膜的微观结构使用扫描电子显微镜、原子力显微镜、拉曼、X射线衍射光谱等仪器进行表征,其拉伸强度和断裂伸长率也随着退火温度发生了变化。当石墨烯薄膜在1 500℃进行退火时,其拉伸强度和断裂伸长率分别达到了最大值,为22.41 M Pa和2.44%,这可能是由于1 500℃时,石墨烯表面产生了更多的物理锁合位点。关于石墨烯薄膜退火温度-结构-机械性能之间的关系的研究,有望为石墨烯薄膜在实际应用中性能的优化提供理论指导。宋宁静 吕春祥 陈成猛 马灿良 孔庆强 2017新型炭材料2017,32,3:4
3Graphene-based bipolar plates for polymer electrolyte membrane fuel cells显示文摘Bipolar plates(BPs)are a major component of polymer electrolyte membrane fuel cells(PEMFCs).BPs play a multifunctional character within a PEMFC stack.It is one of the most costly and critical part of the fuel cell,and hence the development of efficient and cost-effective BPs is of much interest for the fabrication of next-generation PEMFCs in future.Owing to high electrical conductivity and chemical inertness,graphene is an ideal candidate to be utilized in BPs.This paper reviews recent advances in the area of graphene-based BPs for PEMFC applications.Various aspects including the momentous functions of BPs in the PEMFC,favorable features of graphene.based BPs,performance evaluation of various reported BPs with their advantages and disadvantages,challenges at commercial level products and future prospects of frontier research in this direction are extensively documented.Ram Sevak SINGH(El) Anurag GAUTAM Varun RAI 2019Frontiers of Materials Science2019,13,3:3

6Research progress on the characterization and repair of graphene defects显示文摘Graphene has excellent theoretical properties and a wide range of applications in metal-based composites. However, because of defects on the graphene surface, the actual performance of the material is far below theoretical expectations. In addition, graphene containing defects could easily react with a matrix alloy, such as Al, to generate brittle and hydrolyzed phases that could further reduce the performance of the resulting composite. Therefore, defect repair is an important area of graphene research. The repair methods reported in the present paper include chemical vapor deposition, doping, liquid-phase repair, external energy graphitization, and alloying. Detailed analyses and comparisons of these methods are carried out, and the characterization methods of graphene are introduced. The mechanism, research value, and future outlook of graphene repair are also discussed at length. Graphene defect repair mainly relies on the spontaneous movement of C atoms or heteroatoms to the pore defects under the condition of applied energy. The repair degree and mechanism of graphene repair are also different according to different preparations. The current research on graphene defect repair is still in its infancy, and it is believed that the problem of defect evolution will be explained in more depth in the future.Bo-yu Ju Wen-shu Yang Qiang Zhang Murid Hussain Zi-yang Xiu Jing Qiao Gao-hui Wu 2020International Journal of Minerals,Metallurgy and Materials2020,27,9:1
7Edge-oriented MoS2 aligned on cellular reduced graphene for enriched dye-sensitized solar cell photovoltaic efficiency显示文摘The counter electrode (CE) prominence in dye-sensitized solar cells (DSSCs) is undisputed with research geared towards replacement of Pt with viable substitutes with exceptional conductivity and catalytic activity. Herein, we report the replaceable CE with better performance than that of Pt-based electrode. The chemistry between the graphene oxide and ice templates leads to cellular formation of reduced graphene oxide that achieves greater conductivity to the CE. The simultaneous growth of active edge-oriented MoS2 on the CE through CVD possesses high reflectivity. High reflective MoS2 trends to increase the electroactivity by absorbing more photons from the source to dye molecules. Thus, the synergistic effect of two materials was found to showcase better photovoltaic performance of 7.6% against 7.3% for traditional platinum CE.Infant RAJ Daniel KIGEN Wang YANG Fan YANG Yongfeng LI 2018Frontiers of Materials Science2018,12,4:0
