Abstract

The invention relates to a method for carrying out surface modification on a polyether-ether-ketone material and the modified polyether-ether-ketone material. Based on the electron beam evaporation technology, biological ceramic with silicon is adopted as an evaporation target, silicon is evaporated and deposited on the surface of the polyether-ether-ketone material, and a modified layer with silicon is obtained. Based on the electron beam evaporation technology, silicon is introduced into the surface of the polyether-ether-ketone material, the method is simple and feasible, the modification effect is excellent, the content of silicon is controllable, and the surface biocompatibility and frame integration of the polyether-ether-ketone material can be greatly improved.

Description

technical field [0001] The invention relates to a method for surface modification of polyetheretherketone materials, in particular to a method for surface modification of polyetheretherketone materials by electron beam evaporation technology, and the surface-modified polyetheretherketone prepared by the method. Ether ether ketone material. Background technique [0002] In recent years, the application prospects of medical polymer implant materials have become increasingly broad. The elastic modulus of medical polyether ether ketone material (PEEK) is the best match with human bone tissue, which can effectively reduce bone resorption and bone atrophy caused by stress shielding effect, and has outstanding fatigue resistance, which is expected to become the first choice to replace titanium and its alloy materials Hard tissue implant materials (Biomaterials 2007, 28:4845-4869.). However, although the PEEK material has good biocompatibility, its biological activity is poor, and...
