METHOD FOR PREPARING CARBON NANO−HORN AGGREGATE

摘要

A method for preparing a carbon nano−horn aggregate, which comprises vaporizing a solid carbon simple substance in an inert gas atmosphere under a controlled pressure corresponding to the atomic or molecular weight of the inert gas to release a carbon vapor into the inert gas, thereby forming a carbon nano−horn aggregate with tips of carbon nano−horns being positioned in the periphery thereof. The method allows each of bud−like and dahlia−like carbon nano−horn aggregates to be prepared individually in high yield.
