摘要

A magnetic composite material is consisted of: a) 10 to 50 grams of a polymer per 100ml organic solvent, wherein said polymer is selected from the group consisting of polylactic acid, polyglycolic acid, lactic acid-glycolic acid copolymer, polycaprolactone, polyamide and poly hydroxybutyric acid; b) 10 grams of hydroxyapatite nanoparticles per 100 ml organic solvent; and c) 2.5 grams of γ-Fe₂O₃ nanoparticles per 100 ml organic solvent, wherein said organic solvent is selected from the group consisting of tetrahydrofuran (THF), dimethyformamide (DMF), dimethylacetamide (DMAc), chloroform and dioxane. The application of the magnetic composite material in the regeneration and repair of bone tissue, the method to prepare the magnetic composite material and the product made from said magnetic composite material are also described.
