METHOD OF MANUFACTURING POROUS METAL SCAFFOLDS COATED WITH POROUS OXIDATION FILM AND POROUS METAL SCAFFOLDS MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing a porous metal support coated with a porous oxide film and a porous metal support produced thereby. More particularly, the present invention provides a method of forming a porous oxide film by an anodic oxidation process using an electrolytic solution in which an alcohol solvent is added to a surface of a porous metal body produced by a freeze casting process. Accordingly, the present invention can increase the fluidity of the electrolytic solution due to the alcohol solvent in the electrolytic solution, thereby forming a porous oxide film to the inside of the pores, and the sediment can not be accumulated in the pores even after the anodic oxidation process, so that the decrease in the porosity can be controlled. In addition, the porous metal scaffold has high biocompatibility, and cell proliferation can be smoothly performed, and the porous metal scaffold can be applied as an implant.
