Abstract

The present invention discloses a honeycomb porous structure titanium dioxide film and a preparation method thereof, wherein titanium base precursor molecules are adopted as a construction motif, a breathing pattern method is adopted, and water drops are adopted as a dynamic template to carry out a surface sol-gel process to prepare the honeycomb porous structure titanium dioxide film. According to the present invention, a pore size of the honeycomb porous structure titanium dioxide film can be dynamically controlled during a material preparation process by changing test parameters, wherein the test parameters comprise a precursor solution concentration, composition of the mixed solvent, a gas flow rate and the like; the honeycomb porous structure titanium dioxide film provides better cell compatibility compared with the titanium foil, and can be paved on the surface of the titanium base implant material so as to improve biocompatibility and biological activity and shorten an osseointegration time of the implant material and the human body.

Description

technical field [0001] The invention relates to a titanium dioxide-coated implant material with a honeycomb porous structure and a preparation method thereof. Background technique [0002] The advancement of modern science and technology has enabled human beings to transform and create new life forms, and the artificialization of organs has become one of the cutting-edge technologies of today's medical science. Its potential core is the development of medical biomaterials. The development of medical biomaterials will enable people to change the methods of dealing with the loss of function of the human body from tissue removal, tissue replacement, and finally tissue reconstruction. In the application of medical biomaterials, hard tissue replacement materials such as artificial teeth, artificial joints and artificial bones account for a large proportion and grow at a relatively rapid rate. [0003] In the research and application of artificial implants, compared with traditio...
