| titleOfInvention | Hydroxyapatite ceramic/graphene composite bone tissue replacement material and preparation thereof |
| abstract | The invention belongs to the field of bone tissue replacement materials, and relates to a porous hydroxyapatite ceramic/graphene composite bone tissue replacement material and a preparation method thereof. The invention provides a preparation method of a hydroxyapatite ceramic/graphene composite bone tissue replacement material, which sequentially comprises the following steps: preparing nano hydroxyapatite/chitosan/graphene slurry, preparing a porous hydroxyapatite/graphene composite scaffold, and sintering and molding; the method for preparing the composite scaffold comprises the following steps: immersing the polyurethane sponge in hydroxyapatite/chitosan/graphene slurry, filling the pores in the polyurethane sponge with the slurry by extruding the polyurethane sponge, taking out and carrying out vacuum drying; in the vacuum drying process, the vacuum temperature is 40-80 ℃, and the vacuum degree is 60-90 KPa. The obtained bone tissue replacement material has a porous structure, has high mechanical strength and porosity, and can meet the requirements of the bone tissue replacement material. |
