AQUEOUS SOLUTION FOR STRUCTURAL SEPARATION OF CARBON NANOTUBES, METHOD FOR SEPARATING AND RECOVERING CARBON NANOTUBES WITH USE OF SAID AQUEOUS SOLUTION, AND CARBON NANOTUBES OBTAINED BY SAID METHOD

摘要

The purpose of the present invention is to provide: an aqueous solution for structural separation, which is capable of separating carbon nanotubes (CNT) having a specific structure with high accuracy by acting on CNT; a separation/recovery method which is capable of separating CNT having a specific structure with high accuracy by causing this aqueous solution to act thereon; and CNT which are obtained by this separation/recovery method. The present invention made it possible to separate CNT having a specific structure with high accuracy by solubilizing lithocholic acid or a lithocholic acid isomer, which is highly hydrophobic and is not soluble in water by itself, and using an aqueous solution that contains this solubilized lithocholic acid or this solubilized lithocholic acid isomer as an aqueous solution for structural separation of CNT.
