Vertically Aligned C60 Microtube Array

Abstract

The liquid-liquid interfacial precipitation (LLIP) process can be modified as kinetic control of precipitation of C60 crystals is possible. In the modified LLIP process, fast precipitation condition gives fine nanowhiskers while slow precipitation induces microtubes. When the precipitation rate becomes very low, C60 crystals nucleate heterogeneously on the separating membrane and grow vertically with a well-developed hexagonal-shaped cross section and <110> crystallographic direction.
