▎ 摘　　要

NOVELTY - A medical artificial bone material comprises 20-50 pts. wt. graphene oxide, 20-75 pts. wt. 3-phenylacryloyl chloride, 50-100 pts. wt. methyl methacrylate, 0.5-2 pts. wt. catalyst, and 0.5-2 pts. wt. initiator. USE - Medical artificial bone material (claimed). ADVANTAGE - The medical artificial bone material is prepared by simple process at low cost, greatly enhances the strength of medical artificial bone material, inhibits the growth of bacteria, and does not affect the compatibility of artificial bone and human biological tissue. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of medical artificial bone material, which involves (i) dispersing graphene oxide in a 3-phenylacryloyl chloride solution, adding into a reactor, adding catalyst, reacting at 70-100 degrees C for 3-5 hours under argon protection atmosphere, (ii) adding methyl methacrylate to the reactor, heating at 100-200 degrees C, adding initiator, reacting for 6-10 hours, and cooling to room temperature.
