Abstract
An apparatus for forming a carbon nanotube sheet is provided. The apparatus includes a bath and a driving unit wherein the bath has a bottom surface and is configured to contain a carbon nanotube colloidal solution. The bottom surface is capable of having an array of capillary tubes. The driving unit is configured to drive at least a part of the carbon nanotube colloidal solution out of the bath through the array of capillary tubes.
Claims19
An apparatus for forming a carbon nanotube sheet, comprising:
- a bath including an interior surface and an exterior surface, wherein the interior surface of the bath is configured to contain a carbon nanotube colloidal solution;
- an array of capillary tubes extending from the interior surface of the bath through the exterior surface of the bath;
- and
- a driving unit comprising:
- a metal plate disposed external to the bath proximate to the exterior surface of the bath;
- an electrode disposed opposite the metal plate, wherein the electrode and the metal plate are configured to cooperatively generate an electric field across the array of capillary tubes when power is coupled to the electrode and the metal plate effective to drive at least a portion of the carbon nanotubes from the carbon nanotube colloidal solution out of the bath through the array of capillary tubes.

A method for forming a carbon nanotube sheet comprising:
- disposing a carbon nanotube colloidal solution in an interior surface of a bath, the bath having capillary tubes extending from the interior surface of the bath through an exterior surface of the bath;
- and
- driving at least a portion of the carbon nanotubes in the carbon nanotube colloidal solution out of the bath through the capillary tubes by applying a voltage between an electrode and a metal plate effective to produce an electric field across the capillary tubes,
- wherein the metal plate is disposed external to the bath proximate to the capillary tubes,
- wherein the electrode is disposed opposite the metal plate, and
- wherein driving at least the portion of the carbon nanotubes in the carbon nanotube colloidal solution through the capillary tubes facilitates formation of a carbon nanotube sheet on the metal plate.
