  • Irradiation-resistant and anti-wear hydrogen-free carbon film on polymer surface and preparation method and use thereof
    Patent number: 11788182
    Abstract: A hydrogen-free carbon film polymer lubricating material and a preparation method and use thereof are disclosed. In the method, a graphite target is used as the target material, and a magnetron sputtering deposition is performed on a surface of the polymer substrate, thereby physically depositing and forming a hydrogen-free carbon film on the surface of the polymer substrate, thereby obtaining a hydrogen-free carbon film polymer lubricating material.
    Type: Grant
    Filed: January 21, 2022
    Date of Patent: October 17, 2023
    Assignee: Lanzhou Institute of Chemical Physics Chinese Academy of Sciences
    Inventors: Peng Wang, Liqiang Chai, Li Qiao, Xiaogang Bai, Xiaoyu Zhao
