Graphene, material which Nokia and Samsung pursuing applications in electronics and optics

Graphene, practically transparent and a sheet of graphite which is one carbon atom thick, has been the subject of research efforts since 1960s.

It has been touted as 21st Century’s miracle material, which like plastic or Silicon, will have a profound impact on the industry. Graphene promises to outstrip all current nano-materials in the market especially in electronics and energy storage.

Graphene has moved swiftly from the research laboratory to the market place driven by demand from markets where advanced materials are required. This includes the aerospace, automotive, electronics, communication, oil and lubricant sector.

Recently, a new nano-material has been developed by Professor Seung Min Han, Professor Yoo Sung Jeong and Professor Seok Woo Jeon.


The material exhibits hundreds of times greater strength than pure material. The nano-material consists of Graphene inserted in Copper and Nickel.

The result of the research was published in Nature Communications. Professor Han, who led the research efforts, said that the result was astonishing as adding a minute amount of Graphene increased the strength of the material by hundreds of times.

In addition to this, Professor Han said that the new material can be applied to coating material for nuclear reactor construction or other structural material requiring high reliability.

Most Graphene producers currently produce Graphene nano-platelets and Graphene oxide. The producers are generally small, start-up companies who have witnessed an explosion in demand for their materials from a variety of industries.

Companies such as Philips, Nokia, IBM and Samsung are pursuing applications for Graphene in electronics and optics.
