Abstract

The invention discloses an artificial implant co-modified with a porous zinc oxide and tantalum oxide coating, and further discloses a preparation method of the artificial implant co-modified with theporous zinc oxide and tantalum oxide coating. The artificial implant is prepared from a porous ZnO and Ta2O5 coating / TiO2 nanotube array / titanium or titanium alloy matrix, and the TiO2 nanotube arrayarranged on the surface of the titanium or titanium alloy matrix is coated with the porous ZnO and Ta2O5 coating of a micro-nano structure; and the preparation method comprises the steps that a mixedsolution of ZnCl2 and TaCl5 is sprayed on the TiO2 nanotube array on the surface of titanium or a titanium alloy, and then sintering is carried out. According to the artificial implant co-modified with the porous zinc oxide and tantalum oxide coating and the preparation method thereof, the large specific surface area and high adsorption capacity of the TiO2 nanotube array are utilized to uniformly disperse the porous ZnO and Ta2O5 coating and form the micro-nano structure, and the artificial implant is endowed with the disinfection and sterilization effects and good biocompatibility; and according to the preparation method, the nucleation size of the oxides is refined to form the porous ZnO and Ta2O5 coating of the micro-nano structure.

Description

technical field [0001] The invention belongs to the technical field of biological nanomaterial preparation, in particular to an artificial implant co-modified with porous zinc oxide and tantalum oxide coatings and a preparation method thereof. Background technique [0002] Titanium and titanium alloys have good mechanical properties, good corrosion resistance and biological inertness, which have attracted great attention from medical engineers and technicians, designers of medical devices and doctors of various professions. At present, titanium alloys have been widely used in dental and bone implants, as well as intravascular stents. [0003] However, based on the relatively low biological activity of titanium and titanium alloys, methods of surface modification and coating modification are required to improve their osteoinductive ability in order to achieve good osseointegration of implants. Many studies have pointed out that the surface morphology of titanium and titanium...
