▎ 摘  要

NOVELTY - The element has a nanocomposite layer comprising a graphene layer (1) arranged on a polymer layer (2). The graphene layer is heterogeneous and forms a pattern characterized by different levels of absorption of electromagnetic radiation. The graphene layer is two-dimensional with a thickness of one atom or more than one atom or three dimensional. The graphene layer comprises nanotubes arranged in different directions, including parallel or perpendicular to a surface of the polymer layer. USE - Security element for a sensitive document e.g. credit card, driving license, ID card, certificate, banknote and registration certificate (all claimed). Can also be used for a stock exchange certificate, visa, passport and a vehicle registration document. ADVANTAGE - The element provides metallic-dielectric films as simpler and more convenient than to prepare than a purely dielectric film to improve operation properties to apply several layers. The element enables an arrangement of graphene in a nanocomposite structure of a switch to achieve maximum performance of a security chip during use. The element controls time of operation using the document, makes authorization or transaction by the owner of the document, maintains nature of the proximity document and increases safety standards. DETAILED DESCRIPTION - The electromagnetic radiation selected from a group consisting of infrared radiation, visible light and UV radiation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an arrangement of graphene layers in a nanocomponent comprising an elastic graphene nanocomposite layer.
