本发明涉及一种分离碳纳米管的方法，包括：混合溶液的配置步骤，通过混合单壁碳纳米管溶液和含有凝胶过滤层析载体的浆料来设置混合溶液; 将混合溶液搅拌以将半导体碳纳米管吸附在浆料上的搅拌步骤; 过滤所述混合溶液的过滤步骤; 通过混合表面活性剂溶液和其上吸附有半导体碳纳米管的浆料洗脱半导体碳纳米管的洗脱步骤; 以及通过过滤洗脱的半导体碳纳米管分离洗脱的半导体碳纳米管的分离步骤。 当在洗脱步骤中改变表面活性剂的浓度时，改变半导体碳纳米管的直径。 分离碳纳米管的方法能够通过改变表面活性剂的浓度来方便地直接分离碳纳米管，并能够在短时间内进行数量的分离。

The present invention is provided a mixture comprising a mixed solution prepared by relates to a separation method of carbon nanotubes, the mixed slurry and gel filtration chromatography SWNT solution contains a carrier for chromatography; Stirred stirring the mixture so that the semiconducting carbon nanotubes adsorbed to the slurry; Filtering step of filtering the liquid mixture; Elution step of mixing the slurry and the surfactant solution in which the semiconducting carbon nanotubes adsorbed to elute the semiconducting carbon nanotubes; And eluting the separated phase to filter out isolating the semiconducting carbon nanotubes; comprises a, characterized in that the when the interface changing the concentration of the active agent from the eluting step varying the diameter of the semiconducting carbon nanotubes eluted do.
According to the separation method of carbon nanotubes of the present invention, by changing the concentration of the surface active agent it can be separated simply by a carbon nanotube diameter, and it is possible in a short time separation of the mass.
