Characterization of fullerene nanotubes prepared by the liquid–liquid interfacial precipitation method

摘要

C₇₀ nanotubes were prepared by using pyridine and isopropyl alcohol and heated in air at 250?°C in order to eliminate the contained solvents 'heat treated C₇₀'. The C₇₀ nanotubes were also successfully prepared by use of pyridine and isobutyl alcohol. The C₇₀ nanotubes heated at 1100?°C in vacuum became amorphous carbon, but retained the tubular structure. The structural characteristics of these C₇₀ nanotubes are observed through their high-resolution transmission electron microscopy.
