Modification of Surface Mechanical Properties of Polycarbonate by B~+ and O~+ Ions Implantation

    Graphical Abstract
    • Abstract
  • By implanting B~+ and O~+ ions respectively into polycarbonate(PC) plates, the surface mechanical properties such as hardness and wear-resistance of PC are improved. Measurement by Nanoindenter Ⅱ shows that the hardness of samples increases 7～25 times than that before implantation. The wear-resistance was tested by ball crusher, the narrowest width of the wear-streak decreases for 1/3～1/2. The measurement by Fourier Transform Infrared Spectroscopy(FTIR) indecates:the structure of polycarbonate changes after implantation.
