Graphene

For those of you who have any technical background this material will blow you away, if you haven’t already had that experience from prior knowledge of it. It blew me away at the time.

What is Graphene?

Not to be confused with Graphite, Grapheme, Graphane, or Graphyne.

Graphene is an atomic-scale hexagonal lattice made of carbon atoms.

Graphene is an allotrope (form) of carbon consisting of a one layer thick hexagonal lattice with one atom at each vertex. It is the basic structural element of many other allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes.

It can be considered as an indefinitely large aromatic molecule, the ultimate case of the family of flat polycyclic aromatic hydrocarbons.

Take the trouble to log into Manchester University’s web site to read about the discovery and watch their videos Really fascinating. This is where it all began.

Graphene is a new 2D material which was isolated in 2004. It was discovered after scientists at The University of Manchester, England, separated one atomic layer of graphite using simple sticky tape.

Graphene was first isolated by Prof Sir Andre Geim and Prof Sir Kostya Novoselov at The University of Manchester. It is the thinnest material known and yet also one of the strongest. It conducts electricity as efficiently as copper and outperforms all other materials as a conductor of heat. Graphene is almost completely transparent, yet so dense that even the smallest atom helium cannot pass through it.

The uses of graphene are limitless and because of its multi-functional properties, graphene can be used in thousands of different applications.

Sporting goods, technology and motor vehicles are just a few of the applications that can be improved with graphene. The constant research being done every day is quickly proving that graphene is truly the material of the future.

Graphene’s flexibility could be used in emerging technologies such as rollerball computers, heat sensitive clothing and flexible phones.

Graphene allows light to pass through it very easily, meaning that we could see TVs built into windows and Sat Navs built into car windscreens in the future of electronics.

One of graphene’s most dynamic properties is its remarkable thinness. At just one atom thick, graphene is so thin that it is extremely flexible and conducts heat and electricity extremely well. To put it into context, graphene is about one million times thinner than a human hair.

Graphene’s thinness lends itself perfectly for the development of future technology. Its high conductivity makes it perfect for aiding in CPU cooling and creating more efficient graphene technology.

Graphene is the strongest material known to man – more than 200 times stronger than steel and stronger than diamonds. The strength of graphene could be used in composites and coatings for applications such as the aerospace and automotive industries.

  1. Wow what a discovery, as you say the uses are endless.
    I suppose it all comes down to cost and will it ever reach the every day market.
    So much has been crushed by major manufacturers in the past.

  2. It’s being developed world wide now by various organisations, who have all come over to Manchester to learn the ropes. The university has taken the view that it won’t / hasn’t patented it so that everyone can utilise what there is and develop it every which way. It will definitely be a viable alternative to all sorts in due course and the cost will diminish as it does.
