二维纳米材料-石墨烯概要.ppt

石墨烯还可以应用于太阳能电池、锂电池、基因测序等领域，同时有望帮助物理学家在量子物理学研究领域取得新突破。 中国科研人员发现细菌的细胞在石墨烯上无法生长，而人类细胞却不会受损。利用这一点石墨烯可以用来做绷带，食品包装甚至抗菌T恤。 用石墨烯做的光电化学电池可以取代基于金属的有机发光二极管，石墨烯还可以取代灯具中的传统金属石墨电极,使之更易于回收。 这种物质不仅可以用来开发制造出纸片般薄的超轻型飞机材料、制造出超坚韧的防弹衣，甚至能让科学家梦寐以求的2.3万英里长太空电梯成为现实。 其他应用 5、应用前景 待续…… * * Electrochemical exfoliation Experimental set-up diagram (left) and the exfoliation of the graphite anode (right). a) TEM, b) FESEM, and c) tapping mode AFM height images of GNSC8P obtained in [C8mim]t[PF6]and water (volume ratio 1:1) as electrolyte and at 15 V applied potential One-Step Ionic-Liquid-Assisted Electrochemical Synthesis of Ionic-Liquid-Functionalized Graphene Sheets Directly from Graphite Adv.
