Video: How is graphene metamaterial created?

Graphene has long been hailed as a "miracle material" with great features like ultra-thin (only one atom equivalent thickness) but super hard (200 times stiffer than steel, though thinner than real film). up to 60,000 times) , superconducting (better conductive than any other material at room temperature) and super durable (harder to break than any material ever known).

Graphene's "invisibility" is due to the help of other materials.

Another special thing about today's world's thinnest graphene, with its wide range of applications, is completely transparent. According to experts, graphene's "invisibility" is due to the help of other materials, in an extremely elaborate and complex manufacturing process.

The following video of the Science Channel will partly reveal the process of creating metamaterials that humans can hardly see with the naked eye:

First, the technician puts a copper leaf along with argon gas into the metallurgical furnace to expel the oxygen separating graphene on the copper leaf. Liquid plastic is then put on copper foil and the whole structure is put into the camera at a speed of about 3,000 rpm.

Then, all copper foil is dipped in different solutions to remove copper and remove any contaminants. But the process of making graphene is not complete. It also requires the operation of a mixture that slides on a silicon chip, evaporates with gold pellets and is subjected to the bombardment of plasma gas.
