▎ 摘  要

NOVELTY - Chemically riveting graphene laminated composite metamaterials comprises polymer material and graphene. The graphene is uniformly distributes in polymer material base body. The composite metamaterials is prepared by cross-linking the two sides of the polymer layer and graphene are along the cross-linking part or graphene micro penetration layer, and chemically cross-linked the other side of the polymer layer with the graphene layer to obtain the product. USE - Used as chemically riveting graphene laminated composite metamaterials. ADVANTAGE - The method produces product: with good lamination effect, and high orientation, where the graphene or graphene oxide and polymer resin and additives were alternately nano-laminated product based on flow dynamics, and based on heat and pressure or energy-ray irradiation conditions of the cross-linking reaction; is simple, and economical; consumes less energy; and utilize large amount of raw materials.
