NOVELTY - The utility model claims a graphene injector, comprising an injector syringe, and a injector piston core and an injector piston rod which are in fit to the injector syringe, wherein the the injector syringe, the injector piston core and the injector piston rod are all made of plastic; the plastic syringe inner surface covered with a layer of graphene film layer; said plastic piston core is covered with a layer of graphene film layer. Because graphene property is stable, and it is not easy to react with such as acid and alkali substance, after adding graphene film layer, can increase the stability of the plastic syringe and plastic piston core, at the same time, because graphene has good mechanical strength and enhances the abrasion resistance of plastic syringe and plastic piston core and prolongs the service life.
