最新一期Nature上关于石墨烯的文章

用氧化石墨烯做成的纸 纸一样的或箔一样的材料用在很多技术应用中，如保护层、化学过滤器和粘合剂等。用碳纳米管做成的、被称为“bucky”纸的东西，有可能将高科技纸的使用延伸到燃料电池等应用中，因为它具有很好的机电性能。现在，一种新型纸样碳纳米组合材料已经研制成功，其硬度、强度和柔性都非常好，它就是“氧化石墨烯”纸，是用以近乎平行的方式相互锁定和排列在一起的纳米尺度的氧化石墨烯层状材料做成的。 Preparation and characterization of graphene oxide paper Dmitriy A. Dikin1, Sasha Stankovich1, Eric J. Zimney1, Richard D. Piner1, Geoffrey H. B. Dommett1, Guennadi Evmenenko2, SonBinh T. Nguyen3 & Rodney S. Ruoff1 Department of Mechanical Engineering, Department of Physics and Astronomy, Department of Chemistry, Northwestern University, 2145 Sheridan Road, Evanston, Illinois 60208-3111, USA Correspondence to: Rodney S. Ruoff1 Correspondence and requests for materials should be addressed to R.S.R. (Email: r-ruoff@northwestern.edu). Free-standing paper-like or foil-like materials are an integral part of our technological society. Their uses include protective layers, chemical filters, components of electrical batteries or supercapacitors, adhesive layers, electronic or optoelectronic components, and molecular storage1. Inorganic 'paper-like' materials based on nanoscale components such as exfoliated vermiculite or mica platelets have been intensively studied2, 3 and commercialized as protective coatings, high-temperature binders, dielectric barriers and gas-impermeable membranes4,5. Carbon-based flexible graphite foils5, 6, 7 composed of stacked platelets of expanded graphite have long been used8, 9 in packing and gasketing applications because of their chemical resistivity against most media, superior sealability over a wide temperature range, and impermeability to fluids. The discovery of carbon nanotubes brought about bucky paper10, which displays excellent mechanical and electrical properties that make it potentially suitable for fuel cell and structural composite applications11, 12, 13, 14. Here we report the preparation and characterization of graphene oxide paper, a free-standing carbon-based membrane material made by flow-directed assembly of individual graphene oxide sheets. This new material outperforms many other paper-like materials in stiffness and strength. Its combination of macroscopic flexibility and stiffness is a result of a unique interlocking-tile arrangement of the nanoscale graphene oxide sheets. [search]石墨[/search] |
