NOVELTY - Preparation of graphene film on titanium or titanium alloy surface involves growing graphene film on a metal base material, obtaining graphene film/metal base material, covering the resultant product with layer of plastic film, obtaining plastic film/graphene film/metal base material, placing in metal dissolution medium for dissolving metal base material, obtaining plastic film/graphene film material, cleaning the resultant product, attaching to titanium or titanium alloy surface, naturally drying for 12 hours, and obtaining plastic film/graphene film/titanium or titanium alloy material. USE - Preparation of graphene film on titanium or titanium alloy surface used as medical implant material.
