Title:
METHOD FOR SEPARATING METALLIC SINGLE-WALLED CARBON NANOTUBE FROM SEMICONDUCTIVE SINGLE-WALLED CARBON NANOTUBE
Document Type and Number:
WIPO Patent Application WO/2014/136981
Kind Code:
A1
Abstract:
Provided is a novel method for separating a metallic single-walled carbon nanotube (SWNT) and a semiconductive SWNT from a SWNT with high efficiency. The present invention is a method for separating a metallic SWNT and a semiconductive SWNT from a SWNT, said method comprising: dispersing the SWNT in a solution containing a low-molecular-weight compound; and then separating the resulting dispersion into a liquid fraction and a solid fraction, wherein the low-molecular-weight compound has an alkyl chain moiety that can act to exhibit solubility in a solvent and an aromatic-ring-containing moiety that can act to interact with the SWNT.
