Abstract
The present disclosure discloses a device and a method for preparing a high-density aligned carbon nanotube film. The device includes a container main body, a buffer partition plate and a solvent lead-out part. The buffer partition plate is located at a lower part of the container main body. The solvent lead-out part communicates with an interior of the container main body through a through hole in a side wall of the container main body and extends to an outside of the container main body. The method includes injecting a carbon nanotube solution into a container; immersing a substrate in the carbon nanotube solution; injecting a sealing liquid that is immiscible with the carbon nanotube solution along the substrate or the side wall of the container main body; and leading the solvent out or pulling the substrate such that the liquid surface of the substrate undergoes relative motion.
