Abstract
The present disclosure discloses a method for forming a high-density aligned carbon nanotube film. The method includes injecting a carbon nanotube solution into a container, and adding a dispersant to form a carbon nanotube-dispersant composite. The method also includes adding a substance that interacts with the carbon nanotube-dispersant composite and then dispersing the obtained carbon nanotube solution using water ultrasonic or probe ultrasonic to obtain a carbon nanotube solution containing a dispersant. Then a large-area or patterned high-quality aligned carbon nanotube film can be formed on a substrate by using processes such as pulling, injection dripping or printing. The method is low-cost and suitable for the preparation of large-area high-density aligned carbon nanotubes, and satisfies various needs for industrial application of carbon-based integrated circuits.
