The invention discloses a photothermal, photodynamic and metal ion synergistic antibacterial material based on magnesium/magnesium alloy/zinc/zinc alloy. The material has a layered structure and is sequentially magnesium/magnesium alloy/zinc/zinc The alloy substrate, the corrosion product film of the substrate, and the calcium-phosphorus-metalloporphyrin coating; the calcium-phosphorus-metalloporphyrin coating comprises 5 to 10 layers in total, and the layers are stacked in sequence, and the next layer is coated on the Above the upper layer; each layer is formed by the mutual adhesion and assembly of calcium-phosphorus coatings induced by metalloporphyrin; the calcium-phosphorus-metalloporphyrin coating is a crystalline coating. The photothermal, photodynamic, metal ion synergistic antibacterial material prepared by the method provided in the present invention has a compact and uniform structure, and not only has excellent corrosion resistance, but also has good anti-corrosion properties. It can overcome the problems of high production cost, high brittleness, poor corrosion resistance and poor biocompatibility of amorphous magnesium alloys. |
