摘要（英）：

The present invention discloses a graphene steel composite material, which comprises steel layers and graphene layers, wherein the steel layers and the graphene layers are alternately stacked, the uppermost layer and the lowermost layer of the graphene steel composite material in a stacked direction are the steel layers, and the two adjacent steel layers are separated by one graphene layer. The invention further discloses a preparation method of the graphene steel composite material, wherein the preparation method comprises: providing a plurality of steel plates; providing a graphene dispersion liquid, wherein the graphene dispersion liquid comprises a graphene sheet dispersion agent and graphene sheets dispersed in the dispersion liquid; alternately stacking the steel plates and the graphene dispersion liquid to sandwich the graphene dispersion liquid between the two adjacent steel plates to form a sandwich structure, wherein the uppermost layer and the lowermost layer of the sandwichstructure are the steel plates; carrying out pressurizing pre-treatment on the sandwich structure; and sintering the pre-treated sandwich structure at a temperature of 900-1100 DEG C. The invention further discloses applications of the graphene steel composite material.
