Abstract
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.
