摘要： 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.

摘要： This invention discloses a method for preparing an antibacterial and dust-removal membrane. The method comprises the following steps: depositing a layer of nano-ZnO on the immersed membrane surface as the seed crystal with the atomic layer deposition instrument (ALD instrument); vertically immersing the membrane covered with nano-ZnO layer in a hydrothermal reactor filled with crystal growth solution, heating it for a period of time, taking the membrane out and cooling it to the room temperate, and removing it from the substrate; finally, heating this membrane in a drier, and purging it with nitrogen to remove the paraffin within the membrane pore to obtain the porous membrane with nano-ZnO arrays growing on the surface.
