▎ 摘　　要

NOVELTY - Metamaterial comprises perfluorotributylamine and graphene nanoparticles, platelets or nanotubes, where the graphene nanoparticles, platelets or nanotubes are evenly distributed within perfluorotributylamine forming a two-tier regular grid with cell dimension of 15-25 nm. USE - The metamaterial is useful as: a lubricant; a shield against radiation and electromagnetic waves; and electric current conductor (all claimed). ADVANTAGE - The metamaterial: (as the lubricant) is capable of maintaining lubrication property within -180-700 degrees C; (as the shield against radiation and electromagnetic waves) is capable of absorbing or/and reflecting radiation within the frequency of 30MHz to 30 EHz; and (as electric current conductor) has the resistance of 0.0002-0.000001 Omega /cm2 at -173-102 degrees C (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing the metamaterial comprising preparing the graphene-capturing surface by means of spreading a mixture of N,N-dimethylformamide and tetrahydrofuran in a volume ratio of 1:1-3:1 over the inner surface of a container made of thermally stable and chemically neutral material e.g. borosilicate glass with silica content of at least 80% and boron trioxide content of at least 13%, heating the inner surface for 7-9 hours at 400-500 degrees C, cooling thus coated inner surface of the container to 25-30 degrees C, preparing a sub-structural liquid by mixing perfluorotributylamine with graphene platelets, particles or nanotubes at the ratio of 1-15 mg of graphene per 1 ml of perfluorotributylamine, spreading the sub-structural liquid over the inner surface of the container, cooling the inner surface of the container to -32 degrees C to -50 degrees C, applying magnetic field with intensity of 0.5-2.5 Tl to the container for 12-24 hours, then, heating the resulting liquid state metamaterial to 20-25 degrees C.
