Preparation method and application of biodegradable material |
| abstract |
The invention discloses a preparation method and application of a biodegradable material, wherein the biodegradable material comprises the following components in parts by weight: modifying alpha-phase calcium phosphate to make alpha-phase calcium phosphate and stearic acid solution mix and ball-mill to obtain the product; the modified montmorillonite/polylactic acid composite material is prepared by adopting an in-situ polymerization method; the modified montmorillonite is prepared by reacting hydroxyl magnesium aluminum pillared agent with montmorillonite and roasting; the zinc-based alloy comprises one or more of Zn-Sr alloy, Zn-Ca alloy or Zn-Ca-Sr alloy. The preparation method comprises the following steps: dissolving the modified alpha-phase calcium phosphate, the modified montmorillonite/polylactic acid composite material and the alloy in an organic solvent at room temperature to form a homogeneous solution; rapidly forming the homogeneous solution at-150-0 ℃; and (4) freeze-drying the molding material to obtain the biodegradable material. The biodegradable material has excellent biocompatibility, biological corrosion resistance and strength, and is applied to bone tissue repair materials. |
