| Outline of Final Research Achievements |
The current research was performed for the following three objectives, i.e., ①to realize superconductivity of fullerene nanowhiskers (FNWs) by doping alkali metals, ②to clarify the growth mechanism of FNWs in the liquid-liquid interfacial precipitation method (LLIP method), and ③to improve the mechanical strength of FNWs. The superconducting C60FNWs were successfully obtained by doping potassium, rubidium and cesium. Further, superconducting wires of C60 were also successfully realized by the powder-in-tube method. The size of C60FNWs was found to depend on the solution volume in the LLIP method combined with the manual shaking method and this mechanism was revealed. In addition, the laser polymerization of C60FNW and the improvement of the mechanical strengthening of C60FNWs by adding C70 were conducted.
