METHOD OF SEPARATING AND COLLECTING CARBON NANOTUBE AND CARBON NANOTUBE

摘要

Metallic CNTs and semiconductor CNTs are efficiently separated from a CNT mixture including the CNTs. In addition, the semiconductor CNTs are separated for each structure in good yield, in a short time, and in a simple manner using low-cost facilities by a method allowing automatic processing as well as mass processing. A plurality of columns filled with gel are connected in series. An excessive amount of CNT dispersion liquid is made to pass through the columns so that only CNTs having specific structures adhere to corresponding columns. The CNTs having different structures are separated by eluting the CNTs using eluant with high accuracy. This method allows simple and high-yield automatic processing as well as mass processing performed in a short time using low-cost facilities.
