Iron-intercalated and tetradecyl-edge-functionalized graphene nanoribbon stacks (Fe@TD-GNRs) can be made from commercially available carbon nanotubes by a facile synthesis. The physical properties of the Fe@TD-GNRs were analyzed by transmission electron microscopy, thermogravimetric analysis, X-ray photoelectron spectroscopy, evolved gas analysis, Raman spectroscopy, and scanning electron microscopy. By the intercalation of iron, the alignment of the Fe@TD-GNRs in a magnetic field was enabled. The aligned structures enhanced electrical percolation at given concentrations in previously nonconductive solvents.
通过简便的合成方法，可以从市售的碳纳米管中制备出插层铁和十四烷基边缘功能化的石墨烯纳米带堆叠体（Fe@TD-GNRs）。通过透射电子显微镜、热重分析、X 射线光电子能谱、气相分析、拉曼光谱和扫描电子显微镜对 Fe@TD-GNRs 的物理性质进行了分析。通过铁的插层，使得 Fe@TD-GNRs 在磁场中能够取向排列。在以前不导电的溶剂中，取向结构在给定浓度下增强了电渗滤。
