我们报道了一种由官能化的氧化石墨烯单片高效地制备纳米卷轴的朗缪尔-布洛杰特(LB)方法。透射电子显微镜研究表明，涡旋具有管状结构，其末端没有盖子。涡卷平行于LB设备的移动障碍物对齐，并且在LB压缩过程中呈现出松散-密集的图案。我们发现，特定的溶剂可以解开卷曲的结构。还对排列良好的涡卷进行了电学表征。该方法为以功能化氧化石墨烯为基块的高产量碳纳米线圈的制备开辟了一条新的途径。(C)2010爱思唯尔有限公司。保留所有权利。
We report a Langmuir-Blodgett (LB) approach for highly-efficient fabrication of nanoscrolls from functionalized graphene oxide single sheets. Transmission electron microscope study reveals that the scroll has a tubular structure without caps at its ends. The scrolls align parallel to the moving barriers of the LB equipment and exhibit a loose-dense pattern during the LB compression process. We find that specific solvents can unwind the scrolled structures. Electrical characterization of the well-aligned scrolls was also performed. The method demonstrated here opens up a new avenue for high-yield fabrication of carbon nanoscrolls using functionalized graphene oxide as the building blocks. (C) 2010 Elsevier Ltd.
