| The mean diameter of our starting MWCNTs was ,8nm (Fig. 2a and Supplementary Fig. 1a). For 10 s of Ar plasma etching, our method converted ,20% of the MWCNTs into single- or few-layer GNRs of 10–20-nm width (height,,2nm; see Fig. 2). Other products were multilayerGNRs orGNRs with CNT cores (Fig. 1d). The yield of GNRs was limited by the relatively wide diameter distribution of the starting MWCNTs used (Supplementary Information). All of the width data were obtained after correcting the tip-size effect1. Within the resolution of atomic force microscopy (AFM), the edges of the obtained GNRs were very smooth. Unlike for previous GNRs, the ribbons were uniform in width along their lengths, none being wedge shaped1, owing to the quasi-one-dimensional CNT templates with uniform diameter along their lengths. According to histogram data on GNRs (Supplementary Fig. 1b, c), the widths of our GNRs mostly fell into the range 10–20nm, which is narrower than that of GNRs made by the sonochemical method1. The width of 10–20nm corresponds to half of the circumference of the startingMWCNTs with the mean diameter of,8nm.The heights of ourGNRs were,0.8, 1.3 and 1.8nm, which we assign to single-, bi- and trilayer GNRs, respectively 22. The folding observed in single-layer GNRs (Fig. 2e, f, i) suggests that the flexibility of the GNRs is excellent in comparison with that of MWCNTs. The folds resulted from bending of the PMMA film23 and/or the perturbation of liquid during the removal of the PMMA in acetone. |
