Abstract
The invention discloses a preparation method of a graphene / steel composite material. The preparation method comprises the steps that a dispersive graphene solution is uniformly mixed with a polyvinylpyrrolidone solution to form a graphene / polyvinylpyrrolidone mixed slurry; then the graphene / polyvinylpyrrolidone mixed slurry is sprayed to the surface of steel; later, polyvinylpyrrolidone in a coating is removed by heating; finally a steel material is superimposed, and the graphene / steel composite material is prepared by a hot rolling mode. The graphene / polyvinylpyrrolidone mixed slurry is composited with the steel material, so that the dispersity of graphene can be ensured; then by adopting a hot rolling process, graphene can be uniformly dispersed into a steel material matrix, and the strengthening effect of graphene is exerted. On the premise of ensuring the physical properties of the graphene / steel composite material well, molecular binding between graphene and the steel material is realized. Furthermore, the preparation method is simple in process; the preparation of the mass and large-sized graphene / steel composite material is easy to realize; the production cost is lowered; and the preparation method has excellent application prospects in the fields of automobile anticollision housings, high speed rails, ships, tanks, aircrafts, etc.
Description
technical field [0001] The invention relates to a preparation method of a graphene / steel composite material, which belongs to the field of composite materials. technical background [0002] Graphene is a new type of two-dimensional nanomaterial whose strength is 100 times that of steel. It is difficult to effectively improve the strength of steel materials by traditional methods. Due to the characteristics of graphene, it is also difficult to simply combine with steel materials. By adopting the process method of the invention, the graphene can be well combined with the steel material, and the strength of the steel material is greatly enhanced. Become a new type of graphene / steel composite material with super hardness. [0003] At present, there is no report at home and abroad that adopts this method to prepare graphene / steel composite materials, and the graphene steel composite materials prepared by this process method can be widely used in automobile anti-collision shells ...
