BIOMIMETIC BIOMINERALIZED ARTIFICIAL BONE REPAIR MATERIAL AND PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

Disclosed are a biomimetic biomineralized artificial bone repair material and a preparation method therefor and the use thereof. The material comprises a crosslinked collagen matrix and a biomineralized collagen/hydroxyapatite composite powder dispersed in the matrix. The mass ratio of the collagen matrix to the biomineralized collagen/hydroxyapatite composite powder is 9 : 1 - 1 : 9. The material solves the problems of ready collapsibility, fast degradation speed and poor mechanical properties of materials, and realizes the biomimetic construction of nano-hydroxyapatite and collagen.
