| titleOfInvention | A kind of polyetheretherketone bone scaffold and preparation method thereof |
| abstract | The invention relates to the technical field of 3D printing, in particular to a polyetheretherketone bone scaffold and a preparation method thereof. The interfacial adhesion of PEEK and PLA was improved by adding HAP to PLA and PEEK respectively. At the same time, HAP could enhance the adhesion and growth of cells to the scaffold, and had good biological properties. The texture structure of PEEK‑HAP composite material and PLA‑HAP‑WS composite material were printed by dual nozzles, and the two incompatible materials were fused together by virtue of the fact that the material was still in a high elastic state when it was just extruded. At the same time, the two composite materials are physically interlocked by the textured structure. After implanting into the organism, the two interlock with each other to ensure the mechanical properties at the time of implantation; WS can promote the degradation of PLA. Degradation, cells adhere and grow along the pores left after PLA degradation under the induction of HAP, so that the scaffold always maintains its mechanical properties when it was just implanted. |
