Solvated structure of C60 nanowhiskers

This work characterizes the structure Of C-60 nanowhiskers prepared by the liquid-liquid interfacial precipitation method in the C-60-saturated in-xylene and isopropyl alcohol system. Transmission electron microscopy and X-ray diffraction measurement show that the C-60 nanowhiskers had a hexagonal structure with cell dimensions a = 2.407 urn and c = 1.018 nin which is different from pristine C-60. The structure of the C-60 nanowhiskers in solution is different from that of the solvated structure reported for the C-60 nanotubes but similar to that reported for the C-60 bulk crystal solvated with m-xylene. X-ray diffraction analysis also showed a shift to fcc structure after solvent evaporation. The C-60 nanowhiskers prepared using toluene as solvent also showed a similar-solvated structure, and a more rapid structural change into fcc upon drying was again observed. (C) 2005 Elsevier Ltd.
