Abstract
The object of the present invention is to provide a production method and a production apparatus for a thin film of aligned carbon nanotubes. The present invention relates to a production method for an aligned carbon nanotube film having a film thickness of less than 1000 nm, including a step of causing a part of a dispersion solvent liquid of a carbon nanotube dispersion liquid to permeate to a lower surface side of a filter paper while causing the carbon nanotube dispersion liquid to flow in one direction on an upper surface of the filter paper, and a production apparatus that can be used for said method.

A production method for an aligned carbon nanotube film having a film thickness of less than 1000 nm, comprising:
- installing a liquid flow adjusting plate having a groove extending in a flow direction of a carbon nanotube dispersion liquid to face an upper surface of a filter paper, and
- permeating a part of a dispersion solvent liquid of the carbon nanotube dispersion liquid to a lower surface side of the filter paper while flowing the carbon nanotube dispersion liquid in one direction along the groove in a flow path between the upper surface of the filter paper and the liquid flow adjusting plate,
- wherein the groove is a plurality of grooves extending in the flow path direction of the carbon nanotube dispersion liquid and parallel to each other, and,
- wherein an interval between each of the plurality of grooves is in the range of 0.01 mm and 2 mm.
