Abstract

The invention belongs to the technical field of preparation of antibacterial materials, and in particular relates to a sharp biological titanium material and a preparation method thereof. The preparation method comprises that the titanium material is sequentially subjected to anodic oxidation once, at least three times of equal voltage treatment, and then anodized twice to form TiO 2 Nanotubes, that is, sharp biological titanium materials; at least three equal voltage treatments in this method can remove impurities with poor adhesion and collapsed nanotubes and loose film layers on the anodized surface, which helps to form a highly ordered, pore size arrangement Ideal nanotubes with large specific surface area, and the antibacterial property of titanium dioxide nanotubes after equal voltage treatment is better; and the titanium material prepared by this method can achieve long-term antibacterial effect; the titanium material prepared by the present invention can be used in More active centers can be provided in catalysis, and it has better performance in photocatalysis and photovoltaic cells.

Description

technical field [0001] The invention belongs to the technical field of preparation of antibacterial materials, and in particular relates to a sharp-type biological titanium material and a preparation method thereof. Background technique [0002] Titanium dioxide nanotubes have the characteristics of high specific surface area, high aspect ratio, and size-dependent effect, and have potential applications in various fields, such as solar cells, photoelectrolysis of water, degradation of organic pollutants, and biomedicine.
