Preparation method of surface coating of orthopedic implant instrument |
| abstract |
The invention relates to the technical field of modification of surface coatings of orthopedic implant instruments, in particular to a preparation method of a surface coating of an orthopedic implant instrument, and provides a method for loading and controlling release of copper-citrate nanoclusters on the surface of an orthopedic implant instrument through polydopamine. The preparation method of the coating is simple and convenient, has wide application range, and can be applied to various orthopedic implantation instruments. In addition, the invention can regulate and control the release concentration of copper ions by the poly-dopamine responding to the change of ph value, thereby controlling the conversion between osteogenesis and antibacterial functions of the implantation instrument. |
