▎ 摘　　要

NOVELTY - Graphene modified bioceramic scaffold material comprises beta -tricalcium phosphate scaffold and a graphene layer uniformly coated on the surface of the beta -tricalcium phosphate scaffold. USE - Graphene modified bioceramic scaffold material is useful for the preparation of material for repairing bone and treating bone tumor (claimed). ADVANTAGE - The graphene-modified bioceramic scaffold material exhibits excellent antitumor ability and osteogenic characteristics and improved photothermal property to kill residual tumor cells. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for the preparation of the graphene modified bioceramic scaffold material, which involves fully mixing beta -tricalcium phosphate powder with binder to obtain beta -tricalcium phosphate scaffold by a three-dimensional printing technology, sintering the printed beta -tricalcium phosphate scaffold to obtain a beta -tricalcium phosphate ceramic scaffold, soaking the beta -tricalcium phosphate ceramic scaffold in a graphene solution, and drying to obtain graphene modified bioceramic scaffold material.
