Method for manufacturing a carbon nanotube

摘要

The present invention relates to a nanocapsule-type structure having an average particle diameter of 1 to 50 nm, said nanocapsule-type structure comprising an aqueous solution of a metal compound encapsulated in the inside thereof. Preferably, the nanocapsule-type structure is such that the nanocapsule structure is formed by self-organization of a surfactant in an organic solvent. This nanocapsule structure is in a nanometer size, and high in dispersibility even in a high-concentration region in an organic solvent, and does not undergo aggregation, and it is useful as a catalyst for a CVD method.
