Abstract
The present invention relates to a surface modification method for a polyether-ether-ketone material. The method combines physical and chemical methods, and comprises the steps of performing plasma immersion ion implantation on the surface of the polyether-ether-ketone material with argon as an ion source, and then, soaking the polyether-ether-ketone material treated by plasma immersion ion implantation in a hydrogen peroxide aqueous solution, hydrofluoric acid aqueous solution, or ammonia water to make the surface of the modified polyether-ether-ketone material have nanoparticles, shallow nanoporous structures, and/or ravined nanostructures.
