Title:
METHOD FOR MANUFACTURING HIGH-DENSITY IN-LINE CARBON NANOTUBE THIN FILM
Document Type and Number:
WIPO Patent Application WO/2021/043235
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for manufacturing a high-density in-line carbon nanotube thin film, comprising: injecting a carbon nanotube solution into a container, and adding a dispersant to form a carbon nanotube-dispersant complex; then adding a substance which has interaction with the carbon nanotube-dispersant complex; then dispersing the obtained carbon nanotube solution by using a water domain ultrasonic or probe ultrasonic mode to obtain a dispersant-containing carbon nanotube solution; and then forming a large-area or patterned high-quality in-line carbon nanotube thin film on a substrate by using multiple modes such as lifting, injection and dripping, or printing. The method is low in costs and is suitable for manufacturing of large-area high-density in-line carbon nanotubes, and satisfies multiple requirements in industrial application of carbon-based integrated circuits.
