Abstract:
An embodiment according to the invention provides methods for making interlayer covalent bonds in bilayer, trilayer, and multilayer graphene. Raman spectroscopy is used to characterize the resulting material, and the Raman peak at approximately 1330 cm −1  coincides with the characteristic peak of diamond and polycrystalline nanodiamond peaks published in the art. This indicates that the process induces the formation of sp 3  carbon-carbon (C—C) bonds (similar to the ones in diamond) between the graphene layers. The graphene bilayer or multilayer converts to sp 3  bonded carbon only partially, as the Raman spectrum also indicates a strong component of graphene still remaining in the bilayer or multilayer.

Claim (Index 16):
A method of breaking the planar configuration of graphene in at least a portion of the area of at least two different neighboring layers of graphene to create sp 3  configuration bonds and thereby to create a tetrahedral geometry in at least portion of the carbon atoms of each of the neighboring layers of graphene, the method comprising:\n positioning at least two layers of graphene in a stacked arrangement; and performing a hydrogenation treatment on the at least two layers of graphene to induce formation of carbon-carbon covalent bonds between carbon atoms on different neighboring layers of the at least two layers of graphene for at least a portion of the carbon atoms on at least a portion of the area of the at least two layers of graphene.
