Absstract of: WO2024198803A1
The present application discloses a post-treatment method for greatly improving the performance of a carbon nanotube film, and an application thereof. The post-treatment method comprises: infiltrating an original carbon nanotube film in chlorosulfonic acid for standing, then placing the carbon nanotube film in air such that chlorosulfonic acid molecules inside the carbon nanotube film can react with water molecules in the air, and then generating sulfuric acid molecules inside the carbon nanotube film so as to promote the water molecules to enter the carbon nanotube film; then placing the carbon nanotube film in the chlorosulfonic acid again so as to chemically react with the water molecules to generate a hydrogen chloride gas, resulting in expansion of the carbon nanotube film; and infiltrating the carbon nanotube film in a chlorosulfonic acid solution again after drafting treatment, and finally carrying out high-temperature vacuum annealing heat treatment. The carbon nanotube film prepared in the present application has a tensile strength at the magnitude of GPa and an electrical conductivity at the level of 106S/m, and has a higher surface flatness, such that the compounding of the carbon nanotube film with other materials is facilitated, and a composite interface having a stronger binding force is constructed, thereby greatly improving the final mechanical and electrical properties of a composite material.
