Disclosed is a method for manufacturing a vertically-growing open carbon nanotube thin film. The method comprises: grinding the surface of a ceramic film by using metallographical sandpaper, performing ultrasonic cleaning by using acetone and performing boiling with water, and performing drying to obtain a ceramic film substrate; dissolving a catalyst ferrocene in a carbon source dimethylbenzene in an ultrasonic manner, and adding a carbon nanotube growth promoting agent thiophene to form a mixed solution; putting the ceramic film substrate in a tubular furnace reactor, introducing nitrogen, and slowly injecting the mixed solution at a constant speed to perform a high-temperature vapor deposition reaction; and further performing plasma etching and nitric acid reflux heating treatment to open closed ends of carbon nanotubes, and removing catalyst particles on the carbon nanotube thin film to obtain the open carbon nanotube thin film that is highly vertically aligned. The process of the present invention is simple, practical and low in cost, and the density and the shape of the carbon nanotube thin film can be controlled by changing condition parameters. The prepared carbon nanotube thin film can be widely applied in the fields of gas purification and storage, heat conduction, electric conduction, catalyst carriers and the like, and has good application prospects. |
