▎ 摘　　要

NOVELTY - A medical titanium material surface modification method involves preparing graphene film on surface of medical titanium material. USE - Method for modifying surface of medical titanium material. ADVANTAGE - The method enables modifying surface of medical titanium material in a simple manner by achieving easy industrialization and preparing graphene film, thus improving cell compatibility of medical titanium material surface and biological activity and inducing osteogenic activity of bone marrow mesenchymal stem cells to differentiate into osteogenic cells. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a surface modified medical titanium material comprising medical titanium material and graphene film bonded to surface of the medical titanium material.
