▎ 摘　　要

NOVELTY - The method (S102) involves adding (S104) a first material layer to the surface of the implant substrate. The first material layer is provided with a metal material. A second material layer is formed (S106) on the surface of the first material layer, after pre-treating the graphene material. The second material layer is made of a graphene material. USE - Method for preparing graphene-based medical implant (claimed). ADVANTAGE - The complicated preparation process caused by the need to prepare mixed and uniform composite solution can be solved, so that good use of the biocompatible properties of graphene can be achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene-based medical implant. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the process for preparing graphene-based medical implant.
