Embodiment 1
[0061] After polishing, the 10mm×10mm×1mm carbon fiber reinforced polyether ether ketone was cleaned ultrasonically with acetone and deionized water in sequence, each time for 30 minutes. After cleaning, it was dried in an oven at 80°C and stored properly. Using plasma immersion ion implantation technology, zinc ions were implanted into the carbon fiber reinforced polyetheretherketone matrix. The specific process parameters are shown in Table 1, and the obtained sample number was Zn-180.
[0062] Injection bias (kV) 30 Pulse width (μs) 450 Injection time (min) 180 Background vacuum (Pa) 3.5×10 -3 Cathode trigger pulse width (μs) 500 Frequency (Hz) 8
Embodiment 2
[0064] After polishing, the 10mm×10mm×1mm carbon fiber reinforced polyetheretherketone is ultrasonically cleaned with acetone and deionized water, each time for 30min, after cleaning, it is dried in an oven at 80°C and stored properly. Plasma immersion ion implantation technology was used to implant zinc / oxygen binary ions into the carbon fiber reinforced polyetheretherketone matrix. The specific process parameters are shown in Table 2, and the obtained sample number is Zn-O.

[0068] figure 1 It is the scanning electron microscope morphology of the surface of carbon fiber reinforced polyetheretherketone and unmodified carbon fiber reinforced polyetheretherketone obtained through the modification treatment of Example 1 and Example 2. In the figure: CFRPEEK is unmodified carbon fiber reinforced polyether ether Ketone, Zn-180 is the carbon fiber reinforced polyether ether ketone obtained th...
Embodiment 3
[0070] After polishing, the 10mm×10mm×1mm carbon fiber reinforced polyether ether ketone was cleaned ultrasonically with acetone and deionized water in sequence, each time for 30 minutes. After cleaning, it was dried in an oven at 80°C and stored properly. Using plasma immersion ion implantation technology, zinc ions were implanted into the carbon fiber reinforced polyetheretherketone matrix. The specific process parameters are shown in Table 3.
[0071] Injection bias (kV) 30 Pulse width (μs) 450 Injection time (min) 60 Background vacuum (Pa) 3.5×10 -3 Cathode trigger pulse width (μs) 500 Frequency (Hz) 8
[0072] The surface of carbon fiber reinforced polyetheretherketone obtained by modification has obvious nanoparticle structure, and zinc element can be introduced to the surface of polyetheretherketone by zinc plasma immersion ion implantation, and the zinc element on the surface coexists in the form of elemental zinc and zinc oxide . ...
