El grafeno, ¿material del futuro?

Gaspar Montero

Publicado hace

Graphene is a one atom thick layer of graphite, a modification of carbon. It would be too difficult to go into the peculiarities of the chemical structure.

What matters are the characteristics of graphene:

  • it is the lightest material in the world.
  • 200 times stronger than steel
  • one of the most powerful conductors of heat and electricity.

Where can graphene make a revolutionary difference?

  • Graphene membranes could be used to remove hydrogen gas from the atmosphere. As a result, there are now active developments in the jet fuel segment.
  • Graphene membranes could desalinate salt water. At the same time, their structure would not allow salt to pass through. This could solve the future global water crisis.
  • Corrosion neutralization. Graphene-based paint will create a virtually impermeable coating. The global cost of corrosion would be about $2.5 trillion per year.

Why has it not yet been introduced?

Production costs do not yet allow it. One gram of graphene requires an investment of $100. There are also problems in production in the form of chemical exchange products.

The material is not so popular today, so the market value is about 300 million. However, in 5 years the market will be about $2.8 billion.

IBM has departments to develop graphene, Ford has small divisions. There is even a company in Russia, OCSiAl, a manufacturer of graphene nanotubes, which plans to go public next year.
