| titleOfInvention | A kind of sodium tantalate film layer with biological activity and antibacterial property and preparation method thereof |
| abstract | The present invention provides a surface-modified biometal material with osteopromoting ability and antibacterial ability. The surface modification technology prepares a bioactive film layer co-doped with functional elements calcium and copper on the surface of pure tantalum through the synergistic effect of hydrothermal-molten salt-hydrothermal method (or hydrothermal-hydrothermal-molten salt method). First, a uniform layer of sodium tantalate film was prepared on the surface of metal tantalum by hydrothermal method, and then Ca 2+ was further doped on the sodium tantalate film by molten salt method, and finally Ca 2+ tantalum was doped The tantalum of the sodium film layer is doped with Cu 2+ by secondary hydrothermal, so that a Ca-Cu co-doped film layer with biological activity and antibacterial property is formed on the surface of pure tantalum. The film layer containing calcium and copper prepared by this method is evenly distributed on the surface of tantalum, which is conducive to promoting cell differentiation, improving cell activity, and has certain antibacterial properties, thereby improving the osteopromoting and antibacterial properties of tantalum metal. The field of materials shows a good application prospect. |
