▎ 摘　　要

NOVELTY - Method for preparing calcium phosphate ceramic with in-situ graphene film, involves placing porous calcium phosphate ceramic in a graphene-based material solution, and performing hydrothermal reaction to obtain the product. USE - The method is useful for preparing calcium phosphate ceramic with in-situ graphene film in bone defect regeneration and repair materials (all claimed). ADVANTAGE - The method ensures simple method and simple operation. The ceramic promotes cell adhesion and spread, improves material in vivo bone repair ability, and meets requirements of clinical bone defect regeneration and repair.
