▎ 摘　　要

NOVELTY - The article (100) has a graphene layer (130) arranged over another graphene layer (120), oriented at first interlayer twist angle with respect to the latter graphene layer and bonded by interlayer covalent bonds (125) to the latter graphene layer. Third graphene layer (140) is arranged over the former graphene layer, oriented at second interlayer twist angle with respect to the former graphene layer and bonded by interlayer covalent bonds (135) to the former graphene layer. The interlayer twist angles are equal to 0 degree for formation of a two-dimensional (2D) diamond structure. USE - Multi-layer graphene article i.e. large-area reinforced multi-layer graphene sheet, for ballistic protection of airplane parts in an aeronautics industry. ADVANTAGE - The article achieves twist angle control by growing epitaxially single crystalline graphene monolayers on silicon carbide wafers and subsequently transferring the silicon carbide wafers onto a selected substrate with a specific twist angle, so that the twist angle is accurately controlled by rotating a straight edge of a graphene layer with respect to an adjacent layer by a specific angle, thus ensuring controlled covalent bond densities and spatial distributions between layers for customizing the multi-layer stack, while uniformly increasing shear strength of a bilayer and controllably reinforcing interlayer bonding in the multi-layer stack. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for making an article. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a multi-layer graphene structure including graphene layers.
