Bone regeneration multiple bionic scaffold material and preparation method thereof

The invention relates to a bone regeneration multiple bionic scaffold material and a preparation method thereof. The method comprises the following steps: taking a mixed solution of bioactive nano inorganic particles, water-soluble natural protein and nanofiber bundles as a raw material, and carrying out pre-freezing, freezing treatment, freeze drying and post-treatment to obtain the bone regeneration multiple bionic scaffold material. The bone regeneration multiple bionic scaffold material comprises a lamellar material and an intercalation structure dispersed between layers of the lamellar material, and the intercalation structure is composed of nanofiber bundles and bioactive nano inorganic particles evenly and continuously distributed on the surfaces of the nanofiber bundles; the mass ratio of the water-soluble natural protein to the nanofiber bundle is 20: (2-4); in the multiple bionic scaffold material for bone regeneration, the content of the bioactive nano inorganic particles is 20-35 wt%; the preparat
