半導体型カーボンナノチューブの分離方法、混合溶液および分散液

Japanese Patent JP7308490

B2

To reduce cost for the method for separating semiconducting carbon nanotube from a mixture of metallic and semiconducting carbon nanotubes. The separation method includes preparing a dispersion by mixing a first substance, a second substance, SDS, SC, and a mixture of metallic and semiconducting carbon nanotubes with a solvent, wherein the dispersion into two layers, which are a first layer mainly containing the first substance and a second layer mainly containing the second substance, whereby the semiconducting carbon nanotube is transferred into the first layer, and the metallic carbon nanotube is transferred into the second layer, wherein the first substance is an α-glucan which is composed of glucose linked via α-glucosidic linkage and which has a weight average molecular weight Mw of 4,000 to 7,000 and has a ratio in amount of α-1, 6 linked glucose residues to the entire glucose residues of 40 to 70%.
