Structural characterization of C 60 nanowhiskers formed by the liquid/liquid interfacial precipitation method

The structure of C 60 whiskers fabricated by using the liquid/liquid interfacial precipitation method is analysed with transmission electron microscopy (TEM). The C 60 whiskers with submicrometre diameters, named ‘C 60 nanowhiskers (C 60 NWs)’, contain (002) c planar faults, and the centre‐to‐centre distance between the C 60 molecules along the growth axis of C 60 NWs is shortened ∼1% compared with that of pristine C 60 crystals, indicating the formation of chemical bondings between the C 60 molecules along [110] c ([100] t ) close‐packed directions of the C 60 NWs. The electrical resistivity of C 60 whiskers decreased on decreasing their diameter. This result suggests that the C 60 NWs are electrically conductive. The C 60 whiskers are very flexible and could form a semicircle with a curvature radius of 38 µm.
