SUBSTANCE-INCLUDING CARBON COMPOSITE MATERIAL HAVING CAP EFFECT ANT ITS PRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a carbon nanohorn composite material which can delay the start of releasing of a substance included in a carbon nanohorn from the carbon nanohorn in a solution capable of dissolving the included substance.

SOLUTION: A substance carrier has nanocarbon having an inner diameter of 2-5 nm and an opening having a diameter of 1-2.5 nm in a wall surface. A substance-including composite material is equipped with the substance carrier and a first functional substance included in the substance carrier. A substance-including carbon composite material having a cap effect is obtained by further introducing a second functional substance having a diameter smaller than the inner diameter and larger than the diameter of the opening of the substance carrier having the cap effect into the substance carrier of the substance-including carbon composite material.
