Mass production of low-cost graphene has become possible

The picture shows the latest graphene film prepared by Korean scientists. This work made it possible to mass produce low-cost flexible graphene electronic products.

Since the discovery of graphene in 2004, research and news have not been interrupted.

Graphene is used in a wide range of applications, from flexible electronics to smart clothing, from foldable displays to organic solar cells, and even to future space elevators.

In August 2008, American scientists confirmed that graphene is currently the most intense material in the world.

However, to date, how to prepare large-size, high-quality graphene films is still a difficult problem to be solved.

According to a recent report by The New York Times, Korean scientists have made major breakthroughs in the preparation of large-size, high-quality graphene films.

Korean researchers have recently discovered a method for preparing large-sized graphene films. This graphene film not only has high hardness and high tensile strength, but its electrical properties are also the best among existing materials. These monoatomic layer-thick carbon flakes are very promising materials that can be used to make flexible, ultra-thin electrodes and transistors necessary for flat panel displays. In addition, graphene can also be fabricated into foldable organic light emitting diode (OLED) displays and organic solar cells.

It is reported that the latest graphene film prepared by researchers from Sungkyunkwan University and Samsung Advanced Technology Research Institute is 1 cm thick and has a light transmittance of 80%; it will not break during bending or stretching. , its electrical characteristics will not change.
