▎ 摘　　要

NOVELTY - A three-dimensional graphene/hydroxyapatite hydrogel material is prepared by mixing 6-10 mg/mL graphene oxide solution and 50-200 mg/L hydroxyapatite slurry at 1:0.5-5 mass ratio, reacting at 160-200 degrees C for 0.5-24 hours, cooling to room temperature, and absorbing free water with filter paper. USE - Method for preparing three-dimensional graphene/hydroxyapatite hydrogel material used for bone tissue repairing material and medicine carrier (claimed). ADVANTAGE - The material has high porosity, large specific surface area and excellent mechanical property.
