▎ 摘　　要

NOVELTY - Porous scaffold comprises microspheres, which comprise a polymer blended with a graphene family material chosen from graphene oxide, reduced graphene oxide, and/or their functionalized derivatives. USE - The porous scaffold is used for replacement and/or regeneration of bone tissue, where the replacement and/or regeneration of bone tissue comprises bone grafting procedures including the treatment of segmental bone loss caused by trauma, tumor excision, infection, non-unions, osteonecrosis or developmental deformities for long bone, spinal fusion, craniomaxillofacial, foot and ankle, dental and joint reconstruction (all claimed). No biological data given. ADVANTAGE - The porous scaffold has biocompatible and biodegradable, serves as an effective scaffold for the replacement and regeneration of bone tissue, and has excellent mechanical properties, such as improved mechanical strength, stiffness, and toughness values. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a microsphere comprising a polymer blended with the graphene family material; and (2) a method for producing the porous scaffold or microsphere.
