Title:
カーボンナノチューブの分離方法および分離装置
Document Type and Number:
Japanese Patent JP7349080
Kind Code:
B2
Abstract:
The object of the present invention is to provide a separation method and a separation apparatus for carbon nanotubes capable of separating a mixture of carbon nanotubes in a highly efficient, inexpensive and simple manner. The present invention relates to a carbon nanotube separation method comprising: a step of preparing a dispersion liquid including a mixture of two or more types of carbon nanotubes having different zeta potentials; a step of introducing the dispersion liquid into a flow path formed between a first electrode having holes for allowing the dispersion liquid to pass therethrough, and a second electrode arranged so as to face the first electrode; a step of applying a DC voltage to the first electrode and the second electrode while the dispersion liquid is flowing through the flow path; and, a step of continuously collecting a dispersion liquid including carbon nanotubes separated to a first electrode side upon application of the voltage from an opposite side to the flow path with respect to the first electrode, and at the same time, continuously collecting a dispersion liquid including carbon nanotubes separated to a second electrode side from a downstream side of the flow path.
