SINGLE-WALLED CARBON NANOTUBE SATURABLE ABSORBER PRODUCTION VIA MULTI-VACUUM FILTRATION METHOD

摘要

PURPOSE: A method for preparing a single-walled carbon nanotube saturated absorber is provided to flatten the surface of a carbon nanotube thin film by preparing the carbon nanotube thin film based on a multi-vacuum filtration method and coating two surfaces of the carbon nanotube thin film with polymer. CONSTITUTION: A method for preparing a single-walled carbon nanotube saturated absorber comprises the steps of: filtering a carbon nanotube mixed solution in a vacuum chamber with a membrane filter (20), and depositing a carbon nanotube thin film (10) on the membrane filter; separating the membrane filter from the vacuum chamber, and drying the membrane filter; dissolving the membrane filter to be removed by etchant (400); replacing the etchant with distilled water (500); sinking a lower polymer film (30) on the bottom of the carbon nanotube thin film; depositing the carbon nanotube thin film on the lower polymer film by removing the distilled water; and coating an upper polymer film on the carbon nanotube thin film.
