Abstract
Disclosed are a method and an apparatus for separating metallic CNT and semiconducting CNT, comprising treating with a physical separation means of centrifugation, freezing-thawing-squeezing, diffusion, permeation or the like using a gel containing CNT as a dispersed and isolated state (CNT-containing gel), to thereby make semiconducting CNT exist in gel and make metallic CNT exist in solution.
