Abstract

Nanocrystalline and nanometer-size fullerene particles have been generated by aerosol routes starting from a solution of mixed fullerene extract in toluene. Nanocrystalline fullerene particles have been produced by spray drying, and ultrafine particles have been formed by vapor condensation. Gas-phase particle size distributions were determined with a differential mobility analyzer, and particle morphology and crystallinity were studied by scanning and transmission electron microscopies. When the processing temperature was increased from 20 to 400 degrees C, the average particle size was reduced from 140 to 100 nm due to particle densification. At higher temperatures of 500 and 600 degrees C, nanometer-size (about 20 nm), spherical fullerene particles were formed via vapor condensation. Transmission electron microscopy analysisindicated that a few nanometer-size crystallites were formed already at 200 degrees C and the crystallite size was increased to about 10 nmat 500 degrees C.
