The invention discloses a 4D printed polyetheretherketone/niobate composite material and a preparation method thereof, which are mainly used for trauma and bone repair in the field of biomedicine, such as skull repair, vertebral body replacement, biological support, and the like. PEEK powder and niobate powder can be blended to make PEEK/niobate composite material or coated with niobate material on the surface of PEEK/niobate The surface of the salt composite material is coated with a biodegradable polymer material to obtain a PEEK-based composite material, and the shape structure of a biological implant is formed by 3D printing technology. The polyether ether ketone composite material in the present invention has the characteristics of promoting the formation of calcium and phosphorus salts on the surface of implants, proliferation and differentiation of bone cells, cell adhesion, non-toxicity, good biocompatibility, simple preparation method and the like. |
