Abstract
A manufacturing method for carbon nanotube composite film is disclosed. The method comprises steps of: providing a substrate; coating a first aqueous solution dissolved with a charged polymer on a substrate to form a polymer film; dispersing a single-wall carbon nanotube powder into a second aqueous solution dissolved with a charged compound in order to obtain a semiconductor-type single-wall carbon nanotube aqueous solution, and charge properties of the charged compound and the charged polymer are opposite; coating the semiconductor-type single-wall carbon nanotube aqueous solution on the polymer film; after standing for a predetermined period of time, washing with a deionized water to remove an unabsorbed semiconductor-type single-wall carbon nanotube and excess charged polymer; and air drying, forming a carbon nanotube film on the polymer film. A manufacturing method for carbon nanotube TFT and a carbon nanotube TFT are also disclosed. The carbon nanotubes can be well tiled onto the substrate.
