▎ 摘  要

NOVELTY - Pillared graphene fabrication (94) comprises: constraining at least one layer of multiple fullerenes (92) between alternating layers of graphene sheets (98) at attachment points; and applying energy to break carbon-carbon bonds and open holes in the fullerenes and the graphene sheets at the attachment points and chemically reform carbon-carbon bonds between the fullerenes and graphene sheets around the perimeter of the holes to form open nanotubes (96) that are conjoined between the graphene sheets. USE - The method is useful for pillared graphene fabrication. ADVANTAGE - The method provides fabrication of more complex nanostructures assembled in alternating fashion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for pillared graphene fabrication, comprising: alternating at least two or three layers of graphene sheets and at least one or two layers of fullerenes to form a protostructure that has a total Gibbs free energy (GFE), where each layer of fullerene is constrained between a pair of graphene sheets at attachment points, where the fullerenes comprises carbon-carbon double bonds that present an energy barrier to reorganization of the protostructure to a lower GFE; functionalizing the attachment points between the fullerenes and graphene sheets in the protostructure with tether molecules to add chemical energy to lower the energy barrier at the attachment points; and applying additional energy to the protostructure to overcome the lowered energy barrier and break carbon-carbon bonds and open holes in the fullerenes and the graphene sheets at the attachment points and chemically reform carbon-carbon bonds between the fullerenes and the graphene sheets around the perimeter of the holes and reorganize carbon-carbon bonds within the fullerenes to form open nanotubes that are conjoined between the graphene sheets to form a stable unitary pillared graphene nanostructure having a lower total GFE than the protostructure. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of sequential fabrication of multilayered pillared graphene.
