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