Surface rubidium-doped titanium material as well as preparation method and application thereof

The invention relates to a surface rubidium-doped titanium material as well as a preparation method and application thereof. The preparation method comprises the following steps: cleaning a titanium material after alkali hot treatment to be neutral, drying, then soaking in a rubidium salt solution for reaction and obtaining a titanium material after rubidium salt treatment; calcining the titaniummaterial after rubidium salt treatment at a temperature of 500-750 DEG C to obtain the surface rubidium-doped titanium material; in the rubidium salt solution, the concentration of rubidium ions is 1-10 mol/L. The surface rubidium-doped titanium material provided by the invention has a staphylococcus aureus growth resistance function, is good in biocompatibility and free from cytotoxicity, does not affect the cell proliferation and has a good effect on inducing osteoblastic differentiation of preosteoblasts. The material has antibacterial property and biocompatibility and can effectively solvewound infection and other
