▎ 摘　　要

NOVELTY - A graphene/dual-phase calcium phosphate composite material is obtained using graphene nanosheet as tough phase and dual-phase calcium phosphate as substrate in mass ratio of 0.5-2.5:97.5-99.5. USE - Graphene/dual-phase calcium phosphate composite material. ADVANTAGE - The graphene/dual-phase calcium phosphate composite material has high mechanical property, flexural strength of 151.82 MPa and fracture toughness of 1.74 MPa. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/dual-phase calcium phosphate composite material, which involves using cetyl trimethyl ammonium bromide, graphene nanosheet and dual-phase calcium phosphate.
